1. get any means of non-local auth setup (as i doubt that is ldap related)
2. setup an arma server on a server using that auth for unix users (might even work on the same server; have not tried to reproduce that way)
3. start it (it may segfault if its 64 bit and 32 bit pam libraries for the Authentication source are missing)
4. if 3. does not apply due to 32 bit Target OS, shut down the Authentication source -> Segfault.
