Overview#

Schema Extensions are ways to Extend the LDAP Schema to add more functionality.

Generally, you should try to find existing Schema Extensions for what you wish to accomplish rather than going and modifying the LDAP Schema with custom Schema Extensions.

Creating Schema Extensions is as much an art as a science and we believe should be left to the more experienced.

Depending on your LDAP Server Implementation modifying the LDAP Schema could be irreversible.
