LinuxQuestions.org - Apache + NIS +SVN authentication

I have apache to handle svn authentication(all users have rw) via the perl NIS handler, that part works fine. What I need to do is go a step further and make it so certain(NIS) group members or users only have READ access.

Code:

<Location /svn>

  DAV svn

  SVNParentPath /var/www/svn

  AuthType Basic

  AuthName "The SVN Server!!"

  PerlAuthenHandler Apache2::AuthenNIS

  PerlSetVar AllowAlternateAuth no

  <LimitExcept GET PROPFIND OPTIONS REPORT>

      AuthType Basic

      AuthName "The SVN Server!!"

      PerlAuthenHandler Apache2::AuthenNIS

      PerlSetVar AllowAlternateAuth no

      Require valid-user

  </LimitExcept>

  <Limit GET PROPFIND OPTIONS REPORT>

      AuthType Basic

      AuthName "The SVN Server!!"

      PerlAuthenHandler Apache2::AuthenNIS

      PerlSetVar AllowAlternateAuth no

      Require pixel

  </Limit>

</Location>

Something like this, but this example seems to disallow any methods. How can I go about doing this and still use apache/NIS auth?
