Acc

acc is a command-line utility used to view the content of, and make changes to, the UDB. When run by non-privileged users it cannot make changes. It is often used by scripts.

This page discusses the New UDB version of acc. The Old UDB version is similar, but is mostly of historical interest.

When run without arguments

When run without arguments the acc command returns information about the user which ran the command.

Some of this comes from CSE's own UDB database, while some — particularly the personal and UNSW-specific information — is obtained by acc via LDAP queries to UNSW's Active Directory servers.

acc runs as root using priv which allows it to access private credentials to access the UDB's PostgreSQL database, and UNSW service account credentials to access Active Directory.
