Lsxldap

In Domino 6.0.3 we did our LDAP searches to external Directories via an LSXLDAP.DLL that can be found in the Sandbox. This dll is not working anymore in Notes 6.5.2.

How can we do a search in an external directory that is accessible via LDAP? How can this be handled in Lotusscript with usage of a login and password.

Any ideas?
