Hi,

I had to change code to authenticate users in my organization's LDAP directory. Indeed, accounts are distributed under several organizational units in my LDAP directory.

The current version of the code can't authenticate accounts when these are in different organizational units. Hence my contribution.

I Use a read account to request LDAP to locate the account that has logged in (with e-mail address in the search filter).

I get the number of LDAP entries. If I have one entry then I call ldap_get_dn function to get the DN account and then I call ldap_simple_bind_s using the account's DN and password to perform LDAP authentication.

I changed configuration file elogd.cfg. I added two parameters:

LDAP DN user = <DN read account>

LDAP PW user = <password read account>

I changed code auth.c too (see attached file)

I had to change Makefile. I added a call to lber library

ifdef USE_LDAP
ifneq ($(USE_LDAP),0)
CFLAGS += -DHAVE_LDAP
LIBS += -lldap -llber
endif
endif

Have good day

Hi Stefan,

I enclosed a patch for RPM build process available on GIT.

changes :

  • rpmbuild :
    • checks if provider or custom build (the rm/mv are done on your computers only :-))
    • call rpmbuild with version / release given as parameters
  • elog.spec :
    • last changelog entry date is set to build date
    • build with debug for debuginfo rpms (product rpms are normally automatically strimmed)
    • elog.init call /etc/ini.d/functions for RHEL/Centos/Fedora/? dists

 

Todo:

  • add RPMbuild options for ldap/pam/...
  • enclosed git log in changelog automatically (the dream :-))

Hi Stefan,

2nd patch for RPM build which adds :

  • dynamic build options for krb5/ldap/pam/ssl support :
    • for git / non rpm users : 
      • buildrpm version release [-krb5] [-ldap] [-pam] [-ssl]
    • for rpm users using SRPMS (dependances are managed) :
      • rpm -i elog-ver-rel.src.rpm && rpmbuld -bb [--use krb5] [--use ldap] [--use pam] [--use ssl] ~/rpmbuild/SPECS/elog.spec
  • dynamic 2 last changelog entries :
    • last with build information with
      • dynamic user 's info (use your info if builded from PSI, or use %packager from ~/.rpmmacros if exists, or set to username username@ostname)
      • build options list (KBR5, LDAP, PAM, SSL)
    • before last for product changelog of current ELOG version-release
  • customrel flag for local rebuild :
    • release = %elogrel%{?customrel}%{?dist)
    • so custom builder can add --define 'customrel NSA'  at rpmbuild command or in .rpmmacros file -> elog-3.1.4-2.NSA.el7.x86_64.rpm by example.
  • elog version and release are delivered in specfile as default for rebuild (tarball name uses it so it can not be changed for local rebuild from SRPMS).
  • buildrpm uses ~/rpmbuild/SPECS/elog.spec generated from elog.spec.template (elog.spec is deleted in repo, replaced by elog.spec.template).

 

Tested on EL6 and EL7 x86_64 :-)

Bye

Hi Stefan,

2nd patch for RPM build which adds :

  • dynamic build options for krb5/ldap/pam/ssl support :
    • for git / non rpm users : 
      • buildrpm version release [-krb5] [-ldap] [-pam] [-ssl]
    • for rpm users using SRPMS (dependances are managed) :
      • rpm -i elog-ver-rel.src.rpm && rpmbuld -bb [--use krb5] [--use ldap] [--use pam] [--use ssl] ~/rpmbuild/SPECS/elog.spec
  • dynamic 2 last changelog entries :
    • last with build information with
      • dynamic user 's info (use your info if builded from PSI, or use %packager from ~/.rpmmacros if exists, or set to username username@ostname)
      • build options list (KBR5, LDAP, PAM, SSL)
    • before last for product changelog of current ELOG version-release
  • customrel flag for local rebuild :
    • release = %elogrel%{?customrel}%{?dist)
    • so custom builder can add --define 'customrel NSA'  at rpmbuild command or in .rpmmacros file -> elog-3.1.4-2.NSA.el7.x86_64.rpm by example.
  • elog version and release are delivered in specfile as default for rebuild (tarball name uses it so it can not be changed for local rebuild from SRPMS).
  • buildrpm uses ~/rpmbuild/SPECS/elog.spec generated from elog.spec.template (elog.spec is deleted in repo, replaced by elog.spec.template).

 

Tested on EL6 and EL7 x86_64 :-)

Bye

changes :

  • rpmbuild :
    • checks if provider or custom build (the rm/mv are done on your computers only :-))
    • call rpmbuild with version / release given as parameters
  • elog.spec :
    • last changelog entry date is set to build date
    • build with debug for debuginfo rpms (product rpms are normally automatically strimmed)
    • elog.init call /etc/ini.d/functions for RHEL/Centos/Fedora/? dists

 

Todo:

  • add RPMbuild options for ldap/pam/...

I have been trying to get my head around this application module. I assume that after the input is done on this example (ShiftCheck), if goes into the  usual file system directorys for storage? Or is it (or can it) goto another db like sql, flat, etc.?  I also assume that the 'normal' Elog screens we see for input (and output), would be a completely seperate module that you have for (ShiftCheck).. but we do not see them here (as one of the attachments)? I am asking these questions because I am trying to recreate this (type) of input/output system for users, so I would like to know how the 'whole picture' is done with your example here. Thanx again.

Stefan Ritt wrote:

Dear ELOG users,

starting with SVN revision 2328, custom input forms are implemented. This allows application specific formats for check lists etc. In our specific case we had to implement a shift check list, which was quite long. Furthermore the check list should be optimized for an iPad, which we take in the field and record various checks and readings (in our case some gas pressure gauges at the PSI particle accelerator). Since the standard ELOG interface was too inflexible, a completely hand-written form was needed. The form can be activated by the new configuration options Custom New Form, Custom Edit Form and Custom Display Form, one for a new entry, an entry to edit and and entry to display. In our case we used the same form for all three cases. This is how the shift check list looks under the Safari Browser on a PC:

Capture.png

And here is how it looks on the iPad:

IMAG0036.jpg

Each section can be collapsed and expanded (blue arrows at the left), and various internal checks are made before the check list can be submitted.

Implementing such forms is however more something for the advanced user, since you have to hand-write HTML with CSS and JavaScript code. It can then however be a powerful method for check lists. Please find in the attachments the elogd.cfg configuration for that logbook and the shiftcheck.html source code file. It is a bit complicated since the page is a static page, elogd just serves it from the file. This requires all the dynamic functions to be implemented inside the HTML file with JavaScript. To display an entry for example, the JavaScript loads the raw data with the "?cmd=Download" command and the populates the form fields. The collapsing and expanding is done by using CSS properties. The integrated style sheet was optimized for the rendering on an iPad. Rather large fonts were chosen so that the items can be checked easily with your finger tips. Various parameters are sent between the browser and the elogd program via hidden fields and cookies. So only something for experts! But if you go through the effort and hand-write the form, it can be very handy. Note that you have to upgrade to SVN revision 2328 for the three new options.

Hi,

I added possibility for a new verification of required fields in generated Javascript "function chkform()". To do this I added new logbook option "ValidPattern", in which you can set regular expression for an attribute, for example

ValidPattern HexDigits=[0-9a-fA-F]+

If there is a pattern set for required field, then in chkform() function is generated additional verification, if value of the field matches validation regexp.

Changes I made should not decrease performance of elogd. Let me know please if you can add it to regular version.

 

Jacek

Implementing such forms is however more something for the advanced user, since you have to hand-write HTML with CSS and JavaScript code. It can then however be a powerful method for check lists. Please find in the attachments the elogd.cfg configuration for that logbook and the shiftcheck.html source code file. It is a bit complicated since the page is a static page, elogd just serves it from the file. This requires all the dynamic functions to be implemented inside the HTML file with JavaScript. To display an entry for example, the JavaScript loads the raw data with the "?cmd=Download" command and the populates the form fields. The collapsing and expanding is done by using CSS properties. The integrated style sheet was optimized for the rendering on an iPad. Rather large fonts were chosen so that the items can be checked easily with your finger tips. Various parameters are sent between the browser and the elogd program via hidden fields and cookies. So only something for experts! But if you go through the effort and hand-write the form, it can be very handy. Note that you have to upgrade to SVN revision 2328 for the three new options.

 

Thank you very much for this nice example!

I found a little issue with newer ELOG versions: if the authentication is done via session cookies, the submission of the checklist will fail with the error "Cannot open file passwd". This is actually misleading as the cause of the error is the empty user name submitted (since the cookie storing user name and pwd hash is never created) and not the password file itself. This can be worked around by removing the user name and pwd fields in the html form before submitting in case there is a SID cookie around.

The attached shiftcheck.html contains this workaround and seems to be functioning fine on my installation (ELOG 3.1.0).

 

Cheers,

Hanno

Announcing:  elog2sql

elog2sql was created to help translate logbooks created by the program
``elog'' from the native elog flat file format to a MySQL database.  I had a
need to have the elog data in a database, and it appears from the forum that
several others had a similar need.

 I created a set of perl scripts that will allow the translation of elog
logbooks into a MySQL database. The design and implementation of these
scripts are a simple one, and allow the one-time copying of a set of logbooks.

The elog2sql toolkit consists of two scripts. The first script, parsecfg.pl,
reads a elogd.cfg, and creates a sql file that will create a set of db
tables corresponding to elog logbooks. The second script, parselog.pl, takes
a set of elog logfiles, and creates a sql file that will enter the logbook
data into the database. The result is a copy of the elog logbook that can
used as desired inside the framework of MySQL. Attachments are handled by
inserting an entry of the attachment name into an seperate attachment table.
This allows multiple attachments per entry.

You can download the elog2sql program archive at
http://www.davidfannin.com/elog2sql/elog2sql.tar.gz . It contains the
scripts and basic documentation.  You can read the man page at
http://www.davidfannin.com/elog2sql/index.html 


I have also uploaded a copy of the archive here.

  8   Wed Feb 4 11:24:14 2004 Fred Hooperfhooper@sushisoft.comScriptJavascript for Bookmark Link for one-click submission to elogAlphaFebruary 04, 2004 by Stefan Ritt
I have created a javascript to be used as a browser link that allows a one
step cut and paste from a web browser into a elog logbook. 

The intended application is allow a user to do a text selection in a web
browser, then click on a bookmark that automagically pastes the selected
text, the current browser page url, and the current browser page title into
a pre-defined elog logbook.   I do some research where I would like to save
some text from a webpage, but also have a record of where the webpage came
from.  However, you should find that you can extend this script in a varity
of ways for your own application.  

The script is a simple one: it uses javascript in a saved bookmark to get
your selected text, title, and url, and then creates a new browser window
with a elog form, and print the document variables into the form, and then
submits the form to elog.   The key advantage to this approach is that you
can use the "post" command, rather than "get", to submit to the text section
of an elog logbook.  The only way I found now to submit to elog via a
bookmark is using the "get" command, and it doesn't allow entry of the
"text" field, only attribute fields.    

The second major advantage to using POST is that you can submit a much 
large quanity of information ; However, some checking on this leads me to 
believe that the limit is browser and server depended, so YMMV.  However, a 
great discussion on the limits of browsers can be found here: 
http://www.squarefree.com/bookmarklets/browsers.html .

One of the major limits is that IE6.0 browsers have a maxium of 508 bytes
per bookmark - This book runs over 800 bytes, so I suspect tha IE6+ will 
not allow it. I tested the link with Mozilla and Firebird 0.7.

This script will need to edited for you to use with your elog logbook.
The script should be fairly self-explainitory, if you are used to html 
forms and have some exposure to javascript.

You will need to modifiy the following fields:

1) in form action = http://<your_domain.com>/elog/<logbook>/?cmd=New
   
   change the link to point to your specific logbook to be used for entry.

2) the attribute fields need match up with the ones in your logbook.

   The ones listed in the template are Author, Email, Title, and URL.

   If you have fixed fields (like Author and Email), then you can
   predefine these fields as shown.  

   I have the page title used as the entry for Title, and the page url is
   use as the URL attribute.

   Finally, I have the text selection used as the entry for the Text field.

   You can add additional fields by creating a new <input ...>  segment
   in the script.  For those more clever than me, you can concatinate the
   title, url and selection to paste into the Text area as well.  

3) once you have a edited version of the script (make sure you keep it as a
single line), you can then create a new bookmark in your browser, and then
paste the script into the properties->location field (for Mozilla/Firebird)
or the properites->url field (IE). Give it a good name like "post to elog"

4) once saved, you can then go a web page, select some text, and then go to
your bookmarks and click on the bookmark. It should then create a new
window in elog with a completed logbook entry.


some notes:

1) again, this may not work on IE6+ browsers due to M$ limitations.

2) You may have to be logged in already to elog for this work - I have not
tested the interaction using a password protected elog

3) You can only post to a single elog logbook - You'll need to have 
multiple bookmarks for multiple logbooks.
