Hi, 

I have a logbook with guest access and guest can also enter a new entry (in config: Guest List Menu commands = New, Find, Select, Login). For other reason in a global section, I put 

Deny New = account1, account2

This somehow invalidates Guest List Menu commands, since as guest I don't see New button anymore. Is this behaviour desired? Otherwise, I would need to move Deny option to plenty of individual logbook configs. Just to explain the reason, those accounts are set up to only read entries and not to create new ones. Or maybe you can suggest a different solution?

Best

Our setup uses "Authentication=Webserver" + no automatic user registration. Thus, logbook admins should add a user by clicking "Config"  and then "New user". However, no matter what they fill in in the "new user " dialog, as soon as they hit "Save" an error pops up saying that their username (the admin one, not the new one) already exists. I found the following code:

int save_user_config(LOGBOOK * lbs, char *user, BOOL new_user)
{
   char file_name[256], str[256], *pl, user_enc[256], new_pwd[80], new_pwd2[80], smtp_host[256],
       email_addr[256], mail_from[256], mail_from_name[256], subject[256], mail_text[2000], str2[256],
       admin_user[80], url[256], error[2000], sid[32];
   int i, self_register, code, first_user;
   PMXML_NODE node, subnode, npwd; 

   /* if we outsourced the authentication, use external username */
   getcfg(lbs->name, "Authentication", str, sizeof(str));
   if (stristr(str, "Webserver")) {
      /* do not allow HTML in user name */
      strencode2(user_enc, http_user, sizeof(user_enc));
   } else {
      strencode2(user_enc, user, sizeof(user_enc));
   }
 

which seems to be the culprit:  the admin user is logged using his/her Webserver (http_user) credentials and this overrides anything that he/she might fill in.  If I remove the "Authentication" check then I can create a new user without problems.  So, how to fix this? should the "Authentication=Webserver" check be extended with a self/auto registration check?

here's the patch that I use to enable  use creation and deletion in combination with Webserver authentication.

The idea behind the patch is that if the user logged in via  "http_user" is an elog admin, then {s}he is allowed to save a random user configuration, including creating or deleting a user.

what is the default value for "Author" when replying to a log entry ?  I now see that for each reply to a log entry, the value of "Author" is set to the value of the author of the original entry - this makes it very hard to see which user has replied to a particular log entry, especially when users start replying to replies etc.

This is with elog 3.1.4-3 on CentOS 7

Excellent, exactly what I was looking for, many thanks!

FWIW: you could cross-compile on Linux using 
   make CC=x86_64-w64-mingw32-gcc CFLAGS="-D_MSC_VER -DHAVE_VASPRintF -Imxml" LIBS="-Wl,--allow-multiple-definition -ladvapi32 -lwsock32 -lssl -lcrypto"
or so I thought... with build 3.1.4 - 395e101 I did manage, finally. 
However, with the latest git version everything seems to have been renamed to .cxx files (though it's still plain C ??!?!?) and my quick and dirty compile hack did not work. The binaries do work, I can start the server and access it via the web interface.

I've built the last C version of elog in git, revision 1ebfd06c using mingw-64 ; the resulting binaries work for me on Windows 2019.
Attached is a zip file with the binaries.
I was not able to create a new installer, these are just the executables

hmmm strange - did you get an error message or did the binary simply not start?  I've only tested this on a single Windows machine....
