DSID-0C090334

Working with our clients on LDAP configuration almost invariable starts with SSL certificates. Self-signed, intermediate, and take up a while. The two tools, openSSL and keytool have become my friends. Working with a network admin for the client, I finally saw the legitimate certificate correctly signed by the intermediate certificate not the self-signed. This means I finally saw this new I error I have never before seen.

javax.naming.AuthenticationException: [LDAP: error code 49 – 80090308: LdapErr: DSID-0C090334, comment: AcceptSecurityContext error, data 525, user@host.domain.tld:    at com.sun.jndi.ldap.LdapCtx.mapErrorCode(LdapCtx.java:3041)

Research on the error code DSID-0C090334 led to indications the LDAP search username was incorrect. The Blackboard CE/Vista LDAP client lacks capabilities many clients have to make it easier to use such as searching deeper into a tree or across branches. In this case our clients configured the user as “cn=account”. We looked at other clients who had something like “cn=account,ou=group,dc=domain,dc=edu”. When presented with this discrepancy as likely a problem, the client suggested a path for us to try like the latter. I entered it, tried our test user.

It worked. They also confirmed it worked. Something to add to the wiki, I guess.
