Yes Brane, I changed the correct subversion configuration file (/etc/httpd/conf.d/subversion.conf) and I also restarted the server using ‘/etc/init.d/httpd restart’ command.

Kedar.

Subject: Re: Can i read/write(based on LDAP group) to SVN without using AuthzSVNAccessFile directive
Hi Brane,
I just found out that it is still referring to ‘/var/www/svn/users-access-file’ even after removing it from subversion.conf. I also deleted ‘users-access-file’ file from ‘/var/www/svn’
I even tried commenting below line from subversion.conf but still same error.
#LoadModule authz_svn_module modules/mod_authz_svn.so
In every case, I am still getting 403 error in logs:
[Tue Sep 05 08:11:33 2017] [error] [client 172.16.2.14] (2)No such file or directory: Failed to load the AuthzSVNAccessFile: Can't open file '/ var/www/svn/users-access-file': No such file or directory
I am not able to understand why it is still referring to earlier configured ‘AuthzSVNAccessFile /var/www/svn/users-access-file’ directive.
Regards,
Kedar.

Thank you, Brane, for your reply.
I updated subversion.conf to include group’s attribute memberUid
AuthLDAPURL ldaps://ldap_l.cisco.com:10648/dc=sprint,dc=com?hasSubordinates,objectClass?sub?uid
AuthLDAPBindDN uid=admin,ou=system
AuthLDAPBindPassword secret
AuthzLDAPAuthoritative on
AuthLDAPGroupAttributeIsDN off
#AuthLDAPGroupAttribute cn
AuthLDAPGroupAttribute memberUid
#<RequireAll>
Require valid-user
<Limit HEAD GET OPTIONS PROPFIND REPORT>
#<RequireAny>
# Read access
Require ldap-group cn=User,ou=groups,dc=sprint,dc=com
#</RequireAny>
</Limit>
<LimitExcept HEAD GET OPTIONS PROPFIND REPORT>

Require ldap-attribute gidNumber=491
#Require ldap-group cn=Admin,ou=groups,dc=sprint,dc=com

</LimitExcept>
#</RequireAll>
I have also updated screen shots for sssd_pb and Roles group. I feel there is something wrong in this ldif because of which it is still not working.
Output of ldapsearch is

Hi Brane,
I tried to follow your suggestions. Please refer attached latest version of ‘subversion.conf’
1. I updated my subversion.conf to include ‘AuthLDAPGroupAttribute’ attribute. Its value is set to cn as cn attribute has the group name (to which user is assigned)
AuthLDAPGroupAttribute is the name of the group's member list attribute, not the user's primary group attribute.
Is there any way I can check for logs? If I get some relevant logs, I myself can dig down more.
You should have Apache server logs available. If they're not detailed enough, you can increase the log verbosity.
I came across below 2 urls which claim that it is not possible to get rid of AuthzSVNAccessFile directive and you must use a file to configure groups and users.
http://grokbase.com/t/subversion/users/1477dcf8yc/how-to-control-access-of-a-subversion-repo-subfolder-via-ad-groups/oldest#responses_tab_top
https://github.com/whitlockjc/sync-ldap-groups-to-svn-authz
Now, I am little confused about whether it is really possible (or not) to fully avoid configuring groups and user names in a separate file.
That depends on what you want to do. If you only want to control read-only vs. read-write access to the whole repository, you can do that in the Apache config, as I showed you. If you want more fine-grained access control, that's what the Subversion authz file is for. If you want to do that per-user, then you will have to define users (and/or groups) in that file. And yes, there are tools out there for automatically generating user and group lists for the Subversion authz file from LDAP.
