Liferay 6.2 - Installations - LDAP integration

Liferay 6.2 - LDAP Integration
*****************************

Liferay 6.2 has no properties files ! Which were there until previous version. I guess now these are part of database tables.

So, while I was trying to integrate my server with LDAP server (TDS) I could configure the LDAP using the Control panel of liferay. And server was able to connect to LDAP.

But due to some issue I was not able to login using any of my ldap users or the default portal user. I was not able to login to the portal.

In earlier version there was a property file named, portal-ext.properties which used to hold those ldap specific values. But this doesnt exist in Liferay 6.2.

While looking at database ( portal database ), I found a table named portalpreferences, which has those ldap properties.

SELECT preferences FROM lportal.portalpreferences where portalPreferencesId = 10160


So, I changed the values of the parameters,
ldap.auth.enabled and ldap.auth.enabled ( which are two check boxes on the LDAP configuration page needs to be checked to enable LDAP login ) to false.

And that's it.

It worked for me, hope it helps you. This is still work under progress and I am looking to complete this LDAP connectivity with Liferay 6.2. So will keep updating this post.
