courier imap can't auth. imap and pop3
 

I setup a mail server using followings components

postfix
sasl
pam-mysql
courier-auth 0.58
courier-imap 4.0.6
mysql 5.0.16

email user is authenicated against mysql backend db
I added a test account in db and I tested the smtp auth and it works (i.e. can authenticate against db)
but I failed to test with imap and pop3

try enabling the "debug" option on the relevant pam lines and see if it kicks anything into dmesg or /var/log/messages.
