Here's a strange one. I have Dovecot set up on Solaris 9. The auth portion of the config is straight out of the box. Using PAM. We have most users in a dbm file which is just a series of key/value pairs: key is a username, and value is a string equivalent to a shadow entry. nsswitch.conf entry: passwd files dbm.
For historical reasons, some users have a classic 13-character Unix crypt password hash, while others have a 34-character MD5 hash. Here's the situation:
User location pw Hash Auth succeeds/fails
files crypt succeeds dbm crypt succeeds files MD5 succeeds dbm MD5 FAILS
After two days of research, trussing, and etc, I am stumped. Does anyone have a thought?
