  What does that mean?  There is no configuration which says "re-use LDAP connections".  It just uses connections from a pool.

  And... you're running Active Directory.

  When the LDAP module gets a redirect from Active Directory, it connects to the other LDAP server.  It does this by re-connecting the existing LDAP connection, instead of creating a new one.

  The server is working as designed.
