I've done some additional testing, the front page in my test wiki is very
simple:
---
====== Test av DokuWiki version 2010-11-07a på Linux ======
Test.
**Endast för testverksamhet. Spara inget viktigt! **
{{NEWPAGE}}
---
The above page takes ~12 seconds to load if AUTH is set to AD, with or without
SSO. Every time.
If I remove the NEWPAGE wiki code (or deactivate the plugin), the page loads in
~1 second.
If I leave NEWPAGE on the front page (and the plugin active) and use kerbsso as
auth backend, the page loads in ~1 second.
The NEWPAGE plugin shows a list of namespaces where you have the rights to
create new pages, so I guess that it has to retrieve all your groups for that.
Since kerbsso (when used in the same wiki) doesn't have any performance issues
it can't be a problem with the Active Directory server, mod_auth_kerb or the
Kerberos client. It has to be in AUTH:AD, probably when group memberships are
retrieved.
Cheers,
Daniel
