Greetings,
I have configuration that is not behaving as I'm assuming it should -
suspect I'm missing a critical detail.
I am using the following setup in a VirtualHost to protect access to a
Mercurial web repo:
<Location /hg>
WSGIProcessGroup hg
AuthType Basic
AuthName "Mercurial LDAP Auth"
AuthBasicProvider ldap
# For AD LDAPS support, requires LDAPVerifyServerCert to be
disabled up above.
AuthLDAPURL [redacted]
AuthLDAPBindDN [redacted]
AuthLDAPBindPassword [redacted]
# Must be off to honor valid-user as "fallback" authorization
AuthzLDAPAuthoritative Off
Require valid-user
AuthGroupFile /etc/httpd/auth/groups
<LimitExcept GET>
#Require group hgpushers
Require group poopy
</LimitExcept>
</Location>
## /etc/httpd/auth/groups
# Authorized to perform Mercurial push operations
#hgpushers: jdoe jdoe2
hgpushers: jdoe
Authentication against LDAP works correctly. Authorization to
'valid-user' works correctly in the normal case. My goal is to use
LimitExcept to restrict Mercurial 'push' operations to members of an
authorized group; this can be done by evaluation of the HTTP methods
as described at
http://mercurial.selenic.com/wiki/PublishingRepositories#Configuring_Apache.
For everything I've tried though, I can still perform push operations
when authenticating as a user not listed in the 'hgpushers' group in
AuthGroupFile (jdoe2 in the above config case). As a test, I also
modified Require to check against a non-existent group 'poopy' and my
authenticated user is still authorized for 'push' operations. it seems
to me that the configuration for LimitExcept as I have is not being
honored. Every change to config at any level is followed by restart of
daemon to apply.
Logging shows the 'hg push' operation concluding with POST requests; I
believe these should be denied.
