Hi Mayank,

dovecot-auth, imap-login and imap were all defunct. The system is using pam_ldap and nss_ldap to authenticate users to a Windows 2003 Active Directory. Immediate restart of dovecot solved the problem for me that day, however since then it's been about 3 times that I've faced this problem. After visiting various forums I came to know one thing, that it has something to do with pam_ldap and nss_ldap. However with UW-IMAP we were using the same setup and we didn't find any problems there.
Following is the system details:
passdb: driver: pam
Not sure if it will solve your problem, but you probably want to set args = blocking=yes in your passdb or switch to direct LDAP queries.
