i currently run multiple trac environments with various different trac versions, including multirepos branch. 0.11 tracs obviously have a single svn repo, while a couple of my multirepos envs have >1 repos attached.
svn is served through apache mod_dav_svn (not svnserve) and i'm using apache authnz_ldap for authentication to everything.
https://server/project/name is my trac project tree
https://server/svn/name is my svn repo tree
authentication configuration is very similar for both:
apache-trac.conf:
<LocationMatch /project[^/]*>
AuthType Basic
AuthName "Security"
<IfModule authnz_ldap_module>
AuthBasicProvider ldap
AuthLDAPURL ldap://server:389/ou=Users,ou=OxObjects,dc=server,dc=domain.net?uid
AuthLDAPGroupAttribute memberUid
AuthLDAPGroupAttributeIsDN off
</IfModule>
</LocationMatch>
# For accessing project list
<Location /project>
Deny from all
Allow from 127.0.0.1 192.168.1. 10.24.0.
Require ldap-group cn=group, ou=Groups,ou=OxObjects,dc=server,dc=domain.net
</Location>
# Individual project access
<Location /project/foo1>
Allow from 10.24.0. 192.168.1. 127.0.0.1 somerandomhost.com
Require ldap-group cn=visitor, ou=Groups,ou=OxObjects,dc=server,dc=domain.net
Require user "andy"
Require user "richard"
Require user "sam"
Require user "bar"
</Location>
apache-svn.conf:
<IfDefine DAV>
<IfDefine SVN>
<IfModule !mod_dav_svn.c>
LoadModule dav_svn_module modules/mod_dav_svn.so
</IfModule>
<LocationMatch /svn[^/]*>
AuthType Basic
AuthName "Security"
<IfModule authnz_ldap_module>
AuthBasicProvider ldap
AuthLDAPURL ldap://server:389/ou=Users,ou=OxObjects,dc=server,dc=domain.net?uid
AuthLDAPGroupAttribute memberUid
AuthLDAPGroupAttributeIsDN off
</IfModule>
</LocationMatch>
<Location /svn>

this configuration could probably be consolidated with regexps, havent gotten around to it.
