Several months I reconfigured the ipp.conf to use the auth_ldap_mod
directive. This has been working flawlessly for months, but last thursday
it just failed!

If I restart apache all is well. Then it will fail again. I cannot see a
problem with the ldap servers, nor am I seeing anthing in the log other

auth_ldap authentication: user..... authentication failed.

One TID suggested that we up the login count. I don't think this is the
problem because reset apache would not affect the login count!
