Ummmm... I wrote a quick perl script to decrypt the string and print it out... I'll have to look at how to tell if there are NUL chars in there. >> 24165 dovecot-auth RET write 9 >> 24165 dovecot-auth CALL read(0xd,0x8550e034,0x2000) >> 24165 dovecot-auth PSIG SIGCHLD caught handler=0x1c02a8f0 mask=0x0 >> 24165 dovecot-auth RET read -1 errno 4 Interrupted system call >> 24165 dovecot-auth CALL write(0x8,0xcfbbfa77,0x1) >> 24165 dovecot-auth GIO fd 8 wrote 1 bytes >> "\0" > > That code is OpenBSD's auth_userokay() call in libc.

I'm not skilled enough in debugging compiled programs to effectively interpret what I see above. Gut instinct - do you think this might be a problem with OpenBSD's lib, or Dovecot, or .. ? I think my configuration is OK, I have tried with both the previous version (that was running under the older Dovecot) as well as migrating my settings to the new Dovecot's version of the configuration. I *really* appreciate all your help. Benny -- "Something's going on in this house - last night, I saw a face!" "Did it have a nose?" "Yes!" "That sounds like a face all right." -- Scary Movie 4
