Openfire configuration error

I’m having a problem with the Openfire configuration. The account is associated with Active Directory, but when I run the test, it can’t reach LDAP and generates the following error:
javax.naming.AuthenticationException: [LDAP: error code 49 - 80090308: LdapErr: DSID-0C09055B, comment: AcceptSecurityContext error, data 52e, v65f4]

This error usually looks like a connectivity issue at first glance, but it’s actually not.

LDAP error code 49 with data 52e from Active Directory specifically means invalid credentials. So Openfire is reaching LDAP - the bind is just failing.

A few things you should check:

  • Bind DN / username format
    Try different formats:
    • Full DN like CN=User Name,OU=Users,DC=domain,DC=local
    • user@domain.local
    • DOMAIN\user
  • Password
    Double-check it carefully (watch for special characters or accidental spaces)
  • Account status
    Make sure the account:
    • isn’t locked
    • isn’t disabled
    • doesn’t have an expired password
  • Test outside Openfire
    Try logging in with the same account on a Windows machine or via another LDAP tool to confirm the credentials work
