plesk, 10.4.4 MU#15, Debian Squeeze 6.0.4, x64
PROBLEM DESCRIPTION AND STEPS TO REPRODUCE
No Login with CRAM-MD5 against POP3, IMAP, SMTP after upgrade.
Starting situation was Debian Lenny 5.0.9 64-bit with Plesk 10.3.1
We updated in the following order:
1.) Upgrade Plesk to 10.4.4 MU#15 lenny-build
2.) Upgrade OS to Debian Squeeze 6.0.4 with autp-get dist-upgrade
3.) Upgrade Plesk to 10.4.4 MU#15 squeeze-build
ACTUAL RESULT
After upgrade, no login for mail-clients with CRAM-MD5 ist possible (bad username/password).
At this moment, we have tested the following ways:
plain password over IMAP -> not work (thats ok)
plain password over SSL/TLS -> work
crypt password CRAM-MD5 over IMAP/S -> both not work
crypt password SHA1 over IMAP/S -> both works
plain password over IMAP -> work
iphone/ipad -> can't test this at the moment,but expected probadly not work, because client requeires CRAM-MD5
EXPECTED RESULT
The mail server should support encrypted password auth like previous plesk versions, in this case CRAM-MD5 works well.
ANY ADDITIONAL INFORMATION
We use standard-setup -> courier-imap and qmail
