We have SVN running via Apache httpd. For authentication we use Active Directory and if the user isn't in AD, we fallback to file authentication. This works fine, except for the error messages in case of file authentication. The error message we get over and over again:
auth_ldap authenticate: user <user> authentication failed; URI /svn/some/uri [User not found][No such object]
We would like to filter out these messages since our log files grows rapidly due to this unnecessary log message.
