[patch] enable AD groups in permissions

Reported by: sandinak Owned by: sandinak
Priority: normal Component: DirectoryAuthPlugin
Severity: normal Keywords: adoption-request
Cc: rjollos Trac Release: 0.12


This is a combination of ideas from LdapPlugin that will enable AD groups to be used for permissions.

  • groups are prefixed with an '@'
  • spaces are replaced by _
  • recurses up the tree to find parent groups
  • includes the patch from #9219


  • caches the ldap handle so we don't reauth

I have taken this several steps further .. with a complete re-write of the caching system to use the local database .. I am working on the installer for the db now .. but this should work LOTS faster across multiple python/apache instances.

Hold up and i'll send in the new patches.

I'm fairly sure that pacopablo is not seen around trac-hacks these days. Let me know if you'd like to take over maintainership of the plugin per AdoptingHacks.

Cool. You'll just need to do the step listed at AdoptingHacks#HowtoAdoptUnmaintainedHacks, including create a dedicated ticket and post to the mailing list.
