Active Directory and LDAP

To make integration easy, ownCloud ships with an LDAP application that makes existing users, including those from Active Directory, appear in your ownCloud user list, avoiding the need to create separate ownCloud accounts for existing users. 

Users can then authenticate with their existing credentials. The authentication request is handled by the Active Directory or LDAP server, so ownCloud does not store the passwords. The application also simplifies integration by pulling users’ group memberships, quota settings, email adresses and avatar pictures through appropriate queries and filters.
