Hi there,
for me, that threat has lead to the solution.
Because AuthLDAP is not working as long as inside its setting (/wordpress/wp-admin - logon -> Settings -> AuthLDAP -> LDAP URI") relates to the UCS slave host where the Wordpress App is installed. The fact that on the slave host univention-ldapsearch command does not return an error (but AuthLDAP does) has misled me.
After having read this threat I’ve modified the above setting by relating it to the LDAP master host (and domain controller as mentioned by cybersepp) … and AuthLDAP is running as now. Please add that information to your knowledge base if it is a feature and not a bug.
Best regards,
yvde
