[Dovecot] One User Cannot Log In

[Jay Chandler]

Attempting to log in through Squirrelmail.

Jan 19 09:34:07 montreal dovecot: imap-login: Login: user=<steve>,
method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured
Jan 19 09:34:07 montreal dovecot: IMAP(steve): initgroups(steve, 15)
failed: Invalid argument

This entry appears nowhere else in the log.

montreal# id steve
uid=268(steve) gid=15(users) groups=15(users), 626(moodleCreators),
80(www), 98(ident), 28(saweb), 303(helpdeskweb), 53(bind), 86(cgi),
206(oacmail), 70(shakes), 43(xfs), 83(acweb), 10(wheel), 208(nasa),
54(lock), 244(helpdeskadmin)
montreal# id chandler
uid=119833(chandler) gid=15(users) groups=15(users)

We did have the problem of his low UID causing trouble, but I've
temporarily changed the Lowest UID setting in dovecot.conf until we can
get about 200 users moved.

Any suggestions?
