HI!
Lurking on the FDS list I noticed the new "Autobind" feature of FDS for LDAPI connections which directly emulates a SASL EXTERNAL bind if the client connects over LDAPI with a certain user-ID and simple bind (or no bind at all). It's configured at the server's side.
See http://directory.fedoraproject.org/wiki/LDAPI_and_AutoBind
Wouldn't that be a useful feature in OpenLDAP's slapd too for LDAP for automagically binding LDAP clients which aren't capable of sending SASL-Bind EXTERNAL but are capable to connect via LDAPI?
Ciao, Michael.
