FESS 13.15.1/2 - LDAP Auth not working


after upgrading FESS 13.15.0 to .1 or .2 LDAP auh seems to be broken.
With version .0 everything worked fine after upgrade and same settings I get the following log entries in debug level when I’m try to login with ldap user:

I’ve already double checked bind dn/pass etc.

Any suggestions?

You need to merge settings from the latest fess_config.properties. I don’t think your fess_config.properties contains all values.

Thanks, after merging changes from new fess_config.properties into current one everything works fine now.
