I'm chasing this "Insufficient permissions to access /" error for hours in my trac project.

I've googled but so far didn't find any solution yet.

I'll update as soon as I resolve this problem.

UPDATE

I've resolved the problem. The context of the problem might not be applicable for all of the users who encounter this error message. It might depend on the configaration of the trac+svn setup.

IN MY CASE, I have multiple repositories and for trac, and I use global ini file. So, each trac instance inherits the global ini file.

The error came along when I added following segment into my global trac.ini file.

[trac]
authz_file = /path/to/my/svn-auth.ini

So, after commenting those two lines from the global trac.ini, I could browse my code base from the trac.

Hope this might help somebody.
