[1640/4136][Tue Apr 12 2016 14:26:53][SmDsLdapConnMgr.cpp:720][WARNING][sm-Ldap-02900] Function prldap_set_session_option is not supported. <server_name>:port


  • Policy server running on Windows OS
  • User Store configure in AdminUI with AD Provider (NOT LDAP)



Policy server implemented two LDAP providers:

Mozilla LDAP SDK for keystore and session store LDAP connectivity.

UserStore connectivity the namespace can be one of two LDAP SDK’s:

  • ADSI LDAP Provider(Windows PS ONLY) - AD Name space is selected
  • Mozilla LDAP SDK - LDAP namespace is selected

The error message occurs when the AD Name space is selected.  Policy server during user store initialization will check all support LDAP server control options.  The error shown indicates that the specific option is not support by AD provider that is being used. More specifically the prldap_set_session_option() function sets a session option specific to the prldap layer – used only for Mozilla LDAP SDK (name space)


The error occurs only during user store initialization it is benign it can be ignored
