I have a logbook installed on a Windows 64 bit VM server 2008 R2 and can access it fine using the password file.  However when using Kerberos it does not authenticate correctly.  I installed Kerberos and pointed it to the realm an domain controller.  Using KINIT command line it appears to accept my password.  Any help is appriciated.  Perhaps some other diagnostics i could try against the kerberos install

Here is global settings:

port = 49212

ssl = 1 

url = https://my-elog.domain.com:49212/

Authentication = Kerberos, file

Kerberos Realm = DOMAIN.COM

Admin User = me

Max content length = 10485760

Password file = pw.txt

Allow password change = 1  (perhaps this is an issue???)

Also...when adding users to the logbook, do you leave the password blank if using Kerberos?
