Hi all,
following enviroment:
stock debian squeeze + apache2 + gitweb. Apache handles user authentication over ldap.
the apache git-related config is:
--- (taken from the http://www.kernel.org/pub/software/scm/git/docs/git-http-backend.html)
[...] SetEnv GIT_PROJECT_ROOT /mnt/system/git
AliasMatch ^/git/(.*/objects/[0-9a-f]{2}/[0-9a-f]{38})$
/mnt/system/git/$1
AliasMatch ^/git/(.*/objects/pack/pack-[0-9a-f]{40}.(pack|idx))$
/mnt/system/git/$1
ScriptAliasMatch \
"(?x)^/git/(.*/(HEAD | \
info/refs | \
objects/info/[^/]+ | \
git-(upload|receive)-pack))$" \
/usr/lib/git-core/git-http-backend/$1
ScriptAlias /git/ /usr/lib/cgi-bin/gitweb.cgi/[...]
<Location "/git/repo1.git">
# read access
<Limit GET>
require ldap-group repo.writers
require ldap-group repo.readers
</Limit> # write access
<Limit GET PUT POST DELETE PROPPATCH MKCOL COPY MOVE
LOCK UNLOCK>
require ldap-group repo.writers
</Limit></Location> ----------
The ldap group "repo.writers" has "repo.writer" user in it. The ldap group "repo.readers" has "repo.reader" user in it.
Using the "repo.writer" User, i can successfully clone the repo / push into the repo. The appropriate apache-log entries are:
---------------------------------------------------- 10.13.99.59 - - [06/Jul/2012:13:28:57 +0200] "GET /git/repo1.git/info/refs?service=git-receive-pack HTTP/1.1" 401 2427 "-" "git/1.7.2.5" 10.13.99.59 - repo.writer [06/Jul/2012:13:28:57 +0200] "GET /git/repo1.git/info/refs?service=git-receive-pack HTTP/1.1" 200 728 "-" "git/1.7.2.5" 10.13.99.59 - repo.writer [06/Jul/2012:13:28:57 +0200] "POST /git/repo1.git/git-receive-pack HTTP/1.1" 200 754 "-" "git/1.7.2.5" ----------------------------------------------------
But if i try to use the "repo.reader" account to CLONE the repo, then it fails:
output@shell: ---------------------------------------------------- ilya@brick:/tmp $ git clone https://repo.reader@git-host/git/repo1.git Cloning into repo1... Password: error: RPC failed; result=22, HTTP code = 401 fatal: The remote end hung up unexpectedly ilya@brick: ----------------------------------------------------
output@apache-logs ---------------------------------------------------- 10.13.99.59 - - [06/Jul/2012:13:28:13 +0200] "GET /git/repo1.git/info/refs?service=git-upload-pack HTTP/1.1" 401 2427 "-" "git/1.7.2.5" 10.13.99.59 - repo.reader [06/Jul/2012:13:28:13 +0200] "GET /git/repo1.git/info/refs?service=git-upload-pack HTTP/1.1" 200 935 "-" "git/1.7.2.5" 10.13.99.59 - repo.reader [06/Jul/2012:13:28:13 +0200] "POST /git/repo1.git/git-upload-pack HTTP/1.1" 401 894 "-" "git/1.7.2.5" ----------------------------------------------------
The reason why the cloning fails is pretty clear
1. the repo.reader is trying to "POST /git/repo1.git/git-upload-pack", 2. accordingly the rule "<Limit POST>" for "writers" is matching, 3. apache makes a lookup into LDAP and OF COURSE cannot fint the "repo.reader"-User in the group "repo.writers" 4. as a result the 401 is replied by apache.
When i put the "repo.reader" user into the "repo.writers"-group, then, of course, he can clone the repo. But then he also can push into the repo...
The question is now - why, damn, the git client is trying to post something on CLONE!??!
And the second question - how do i solve it?
I need the authenticated read / authenticated writes separation.
Thanks in advance!
Ilya
