Admin4 is a tool for server maintenance via several plugin modules. Currently, plugins for BIND DNS, LDAP, IMAP and PostgreSQL are included. It is designed as a framework, using Python for fast development of plugins and custom modifications.

The DNS plugin should be able to query (axfr) any type of server, and performs updates via DDNS which insures that it won't interfere with other DDNS clients (DHCP, SAMBA4). For Bind 9.7 and up, statistics are supported as well and used to retrieve the server's zones automatically.

The LDAP plugin features browsing and generic editing of all types of LDAP entries with schema support. In addition, high-level editing of objects like users, groups and samba domains is supported. Custom objectClasses and attributes can easily be added.

The IMAP plugin can browse and modify mailbox metadata, such as name, acl and quota.

The PostgreSQL plugin features a nice query tool, a data modification tool and an object browser.
