Authentication fails with password mismatch error whilst trying to login to svn repo. Following is the config for 10-subversion.conf

Tried everything for last 8 hours for nothing seemed to worked including changing the ports. ldapsearch to the the ldap user works fine and returns the value. checked firewall is not blocking the port 389. checked selinux bits as well.

Tried adding the tha authz file in the config to provide specific users from AD access to repos, still doesn't work:

AuthzSVNAccessFile /etc/httpd/conf/access.conf

access.conf file has following config:

[repo:/]
user1 = rw
