Hi

On my Linux machine, I am getting an error when authldap is trying to authenticate an imap login.

The message in /var/log/messages is

Mar 8 14:03:04 object authdaemond.ldap: ldap_simple_bind_s failed: Protocol error

I have made sure that the courier-imap 1.7.0 is linked against the same libraries as the OpenLDAP server v2.1.4 that it is trying to bind against.

My exim mta can talk to the OpenLDAP server fine, and all the various ldap* and slap* commands work fine.

The exact same authldaprc configuration (with changes to point to the correct server) works with my earlier courier-imap 1.4.x and OpenLDAP v2.0.x I have running on my FreeBSD system, and the ldap database it is going against has an identical schema.

I have googled on the error message, but the results did not tell me much, unfortunately.

below, after my name, is the openldap slpad debug info it dumps when the imap tries to authenticate

Any hints or help appreciated

Thanks Chad
