1. Overview This HowTo presents the schema extensions needed by WebADM with most of LDAP directories. Only Active Directory can work with WebADM without schema extensions. WebADM stores most of its related metadata into the LDAP directory on users accounts and into a specific container/OU. 2. Content of the Schema Extension The schema extension is very minimal. It is composed of three object classes (webadmAccount, webadmGroup and webadmConfig) and three attributes (webadmSettings, webadmData, webadmType and webadmVoice).
