Description Mike Quin 2020-06-28 16:48:21 UTC 
If a loop is created in /etc/login.conf, for example by including :tc=default: in the default class, cap_mkdb will issue a warning:

"cap_mkdb: potential reference loop detected"

but still write a non-usable database.

Once this has happened authentication attempts fail with "PAM account management error: Error in service module"
