iManager ERROR: LDAP: error code 13 - Confidentiality Required

This document (7011373) is provided subject to the disclaimer at the end of this document.


Novell iManager 2.7.5
Novell Open Enterprise Server 2 SP 3


After restarting novell-tomcat (on OES2SP3), users were unable to perform particular functions (like change/reset passwords).  The iManager error observed was:

Error: Simple bind failed. You may need to import the certificate from the server.

Creating LDAP context failed:
[LDAP: error code 13 - Confidentiality Required]

The /var/opt/novell/tomcat5/logs/catalina.out file contained the following error: Creating LDAP context failed:
[LDAP: error code 13 - Confidentiality Required]
        at com.novell.emframe.fw.ldap.JndiLdapAuthenticator.authenticate(
        at com.novell.admin.pwdpolicy.AdvancedSetPassword.verifyUserObjectEntry(Unknown Source)
        at com.novell.admin.pwdpolicy.AdvancedSetPassword.execute(Unknown Source)
        at com.novell.nps.gadgetManager.BaseGadgetInstance.processRequest(
        at com.novell.nps.gadgetManager.BaseGadgetInstance.handleAction(
        at com.novell.nps.gadgetManager.GadgetManager.processInstanceRequest(

Finally, ndstrace with +TAGS +TIME +LDAP showed the following:
1105291584 LDAP: [2012/11/13 14:00:32.77] Rejecting unencrypted bind on cleartext port in nds_back_bind, err = 13


To resolve:
  1. Click on "Configure" icon in iManager.
  2. iManager server.
  3. Configure iManager server.
  4. Click on Authentication tab.
  5. Check the option which says "Use Secure LDAP for auto-connection".

Note: you may need to restart novell-tomcat in order to activate this setting - however logging out & back in should be sufficient.

Additional Information

Changing passwords is an NMAS function.  As identified in the iManager 2.7 documentation - section 6.4.6 - NMAS-related plugins can be affected if "Use Secure LDAP for auto-connection" is disabled.
