Authentication Error

0
Rick Contreras (1●1●1) | asked Jul 02 '10, 4:54 p.m.
I have my LDAP configured, but when users attempt to login, we see this error (on the Tomcat window):

Jul 2, 2010 1:23:10 PM org.apache.catalina.realm.JNDIRealm authenticate
SEVERE: Exception performing authentication
javax.naming.CommunicationException: intel.com:389

Any idea what the above means? I have my ldap registry configured to corp.intel.com and using port 3268, but for some reason, it looks like it's trying intel.com:389. How is that configured or possible?

I know this is a quite old question, but I want to leave this for future references.

I faced a few days ago exactly the same problem and it was a headache. I could fix it by adding the adCompat="true" property and changing the port from :389 to :3268 in the server.xml:

...
      <Realm className="org.apache.catalina.realm.JNDIRealm"
            connectionName="<user>"
            connectionPassword="<password>"
            adCompat="true"
            connectionURL="ldap://<server>:3268"
            alternateURL="ldap://<server>:3268"
            referrals="follow"
            roleBase="<your value>"
            roleName="cn"
            roleSearch="(members={0})"
            roleSubtree="true"
            userBase="<your value>"
            userSearch="(something={0})"
            userSubtree="true"/>
...
