Hi,
I ported old LoginLdap 1.3.5 plugin to Piwik 2.x. This is still alpha realease and may contain bugs, so please help to test (not in your live environment ofc.). I did get this one working against Active Directory service as LDAP and also as Kerberos login.
Well done on publishing your plugin! This is a superb example of what can be done with Piwik and we are grateful you took the time and effort to publish it! hope it will be successful 
Thank you matt!
I’ll try to solve issues myself, but I have a small question about disabling and enabling other plugins by a 3rd party plugin - can I do it?
I need to disable “Login” if “LoginLdap” is activated and enable it again, if LoginLdap disabled.
Following code doesn’t do anything and don’t print any errors:
use Piwik\Plugin\Manager;
...
Manager::getInstance()->deactivatePlugin("Login");

Thanks for the report. I created & fixed in ticket Automatically activate/deactivate the 'Login' plugin when activating another Login plugin (eg. LdapLogin) · Issue #4529 · matomo-org/matomo · GitHub
To fix (or should I say “test the fix”) replace core/Plugin/Manager by this file: https://raw.github.com/piwik/piwik/master/core/Plugin/Manager.php
Hope it helps, feel free to repotr other suggestions and bugs in Piwik, we want to make the platform as good as possible!
Thanks matt!
Confirmed as fixed (tu)
