Help debugging libsasl2

[Torsten Schlabach]

Hi!

I have a problem with libsasl2 (2.0.22) and the ldapdb auxprop plugin.

Basically, I am using libsasl2 with Cyrus IMAPd and I am under the 
impression that no request is ever made by the ldapdb auxprop plugin 
against the LDAP server. At least, I have enabled all possible logging 
on LDAP (-1), so I would presume that no matter how faulty my slapd.conf 
might be, I should see the libsasl2 (as part of Cyrus IMAPd) contact the 
LDAP server and do some connect and some search, but none of that is 
happening.

So I put the option

sasl_log_level: 7

into my imapd.conf file.

But I don't see a single extra line in /var/log/debug or /var/log/syslog 
  at all.

So

a) Is there a way to tell that the ldapdb plugin is loaded at all?
b) How do I make debug output from libsasldb2 work?

Any hints would be welcome!

Regards,
Torsten
