SASL Authentication against LDAP

[Lothar Handl <ranger@wizards.at>]

Hello.

First of all, I am new to this list and I hope not to be off topic
with my question.
On my system I try to install Cyrus IMAP and want to authenticate
against my LDAP tree. I tried to configure SASL with the LDAP Patch
directly, but I could not compile it on my SuSE 7.2 Linux. So I chose
to use SASL2 and authenticate via PAM, but it does not seem even to
ask PAM. My imapd.conf looks like this:

postmaster: postmaster
configdirectory: /var/imap
partition-default: /var/spool/imap
admins: cyrus root
allowanonymouslogin: no
allowplaintext: yes
sasl_mech_list: PLAIN
srvtab: /var/imap/srvtab
sasl_passwd_check: pam
tls_ca_file: /var/imap/server.pem
tls_cert_file: /var/imap/server.pem
tls_key_file: /var/imap/server.pem

I followed the instructions in the Cyrus IMAP Howto on tldp.org. I
don't think the failure lies in LDAP directly because nss_ldap and
pam_ldap seem to work on my system.
I hope you can help me. Do you have a recipie or something like that?
Indeed I am not happy with SASL and hope to find another way of doing it.

Greetings, Lothar
