[imp] sql session handlers broken?

[Michael Schout]

Hi.

I'm trying to update my IMP installation from version 3.2.1 to IMP
3.2.2.  When I did this, I recreated the config files from scratch to
make sure that the config files were all up to date.  However, after
doing this, I can not log into IMP.  When I try to log in, I just get
the login form back with error "Your Mail session has expired. Please
login again.".

I am using the 'sql' SessionHandler with a PostgreSQL database.  I am
watching the database and the sessions are definately getting stored
there. The horde log shows:

Feb 26 10:17:43 HORDE [notice] [imp] Login success for XXXX [xxxxxxxxxxxxx] to {xxxxxxxxxxxxxx:143} [on line 92 of "/usr/local/www/webmail/htdocs/horde/imp/redirect.php"]

So the IMAP login is definately working.  If I switch the horde
SessionHandler to 'none' to make it use PHP's file-based session
management, everything works perfectly and I can log into IMP.  So there
appears to be change between IMP 3.2.1 and IMP 3.2.2 that breaks SQL
session handlers.  I searched the IMP mailing list archives and I ses
numerous other reports of this same problem.  E.g.:

http://marc.theaimsgroup.com/?l=imp&m=106910608323916&w=2

But I have not found any solutions in the mailing list archives.  Does
anyone have SQL session handlers working with IMP 3.2.2?  Has anyone
solved this problem?

Thanks.
