Sounds like an MS Outlook 98 bug to me...

This is not a proper solution.  The client may want to attempt another
operation (like a v2 bind).  The server should not arbitarily close
the connection.

The proper solution is to have Microsoft fix their client to attempt
to v2 bind if the v3 bind fails (and to properly ldap_unbind() any
unused LDAP sessions).
