[Web-cyradm] Problem with pam_mysql and FQUN

[Wim Bakker]

Hai

I have a problem with user authentication
pam_mysql can't find my users when I try to use
FQUN.
The problem seems to be with pam_mysql that does not
seem to be aware of login realms
tested with testsaslauthd :
-testsaslauthd -u username -r domain.tld -p password
0: NO "authentication failed"

-testsaslauthd -u username at domain.tld -p password
0: OK "Success."

So when I use username=username and realm=domain.tld
pam_mysql fails and when I do username=username at domain.tld
and forget abour realm= , pam_mysql goes fine. The problem is
that saslauthd uses the first form :
saslauthd[1248]: do_auth         : auth failure: [user=username] 
[service=imap] [realm=domain.tld] [mech=pam] [reason=PAM auth error].

So two possible solutions
either saslauthd should try user=username at domain.tld or pam_mysql
should honour the realm=domain.tld. How do I have to configure
cyrus-imap/web-cyradm or pam
for either one of these solutions.
