Hi,
We've had some issues with auth. /var/log/secure is full of 1000s of these lines:
Jun 4 19:12:08 khan dovecot-auth: pam_unix(dovecot:auth):
authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=
rhost=127.0.0.1 user=user123
Users can usually login OK with their ldap credentials, but
occasionally logins slow to a crawl if not outright fail, esp people
checking mail through Squirrelmail. Things get better after a dovecot
restart. Googling around, I thought if we switched the order or
disabled the second passdb we had configured for our dovecotadmin
account, these failures would go away but that did not happen. Any
thoughts or additional info I can provide? Pardon the unusual install
prefix. We're trying to keep the source install separated from the
ancient dovecot rpm shipped in rhel5.
Thanks, Jurvis
