[horde] Last Login Problems

[James S. Hayasaka]

Hi All,

I'm having a problem with the dreaded "Last Login: Never" symptom. I 
checked the FAQ as well as chasing a number of red herrings, and I still 
can't make it work. We're running horde 3.1.5 with imp 4.1.5. 
Authentication is handled via IMP IMAP login, and preferences are stored 
in LDAP. Everything works fine - users are able to set preferences, 
create filters, etc. Their last login times just don't update. This is a 
fresh installation, and we have not done any version migration - so the 
issue with needing to delete any legacy hordePrefs: last_login 
attributes is not applicable. (I deleted mine, and it was recreated with 
the default "YTowOnt9" string the next time I logged in).

We have three front-end systems behind an f5 load balancer. Each mounts 
the mail spool, and runs a local IMAP process (dovecot), as well as 
running an LDAP instance that is updated from a master server (none of 
the horde components are set up to use these local servers, but I 
thought I would mention it). IMP for each host is set to authenticate 
off of its local IMAP server. Preference updates write to the master 
server, a separate non-load balanced LDAP server. As I said, all other 
preferences seem to be fine. The fact that horde can create the default 
"hordePrefs: last_login" attribute makes me think it's probably not an 
LDAP ACL issue.

I've gone through the horde.log (no errors), the slapd.log (no 
failures), and the httpd/error.log (no errors).

We're running:

RHEL 5 on all systems
horde 3.1.5-1.el5.centos from the CentOS-extras repository (installed 
via 'yum groupinstall horde')
imp-h3-4.1.5-1.el5.centos
openldap 2.3.27
php 5.1.6

All stock RHEL 5, with the exception of the horde packages. Any help 
would be appreciated, this problem is driving me nuts.

Cheers,

-James
