Use your existing LDAP flexible as authentication backend for WordPress
I also tried a half dozen plugins to find one that would simply let me connect to LDAP without a lot of niceties. This plugin works great. Many of the other plugins out there don't seem to be supported any more, some of them are very specific to a specific LDAP schema (like AD). So some things like login will work but groups will not.
This plugin, on the other hand, seems like it should be suitable for any LDAP. The cost of that is one must know LDAP. If you aren't good with LDAP, this probably isn't the best plugin for you and it might feel somehow like it doesn't work or is insufficient.
I'd really be surprised to find any problems here with any LDAP. Mine is 389-DS on FreeIPA, by the way.
...the only LDAP plugin that worked with WP 4.x out of the box (tested half a dozen of them). Superfast and competent support by Andreas Heigl. Very flexible to support various use cases and still with an easy UI. Top class plugin!
I've searched for a nice and easy ldap-support plugin with all advanced features and finally found it.
It allows you to manage the used querys, maps group members to WP roles and so on.
