Bug#552698: sasl2-bin: promblem with pam_winbind

[Alexander Samad]

Package: sasl2-bin
Version: 2.1.23.dfsg1-2
Severity: normal

Hi
I had a working system of cyrus mail using sasl to authenticate users, via pam.
Through pam I was connecting to windows. Since this upgrade to this version it is not working any more.
I have tested with testsaslauth and tested the same userid password with wbinfo -a & -K. thw wbinfo works.

I did a strace saslauthd & a strace winbind. and found thet the saslauthd is disconecting early - well it seems
like winbind is ready to send some more info but the pipe is closed. and auth fails 

with testsaslauthd I am using a test pam conf
auth    required  pam_winbind.so 
auth    required  pam_deny.so
account    required pam_winbind.so
account    required pam_deny.so
