- PAM does work authenticating against Unix system authentication
- because the postgres server is started by a non-root user. In order
- to enable this functionality, the root user must provide additional
- permissions to the postgres user (for reading
- <filename>/etc/shadow</>).
+ If PAM is set up to read <filename>/etc/shadow</>, authentication
+ will fail because the PostgreSQL server is started by a non-root
+ user. However, this is not an issue with LDAP or other authentication
+ methods.
