Samba failing with LDAP backend
 

Hi,
When I add passwd backend = ldapsam:ldap://myserver to my smb.conf and restart Samba, smbd fails. I turned the logging up to 10 to see what is going on, it finds the ldap server, searches for sambaDomain, then the connection is closed. Then it opens a new connection, establishes TLS, tries to do a bind and then panics.
