[exalate-issue-sync]

Description

User Stories

• As a user whos identity is centrally managed, I don't want to have a "Change Password" button in the account setting because all account data should be managed in a central place.

• As identity is centrally managed, I don't want to have a "Add user" button in the admin settings because all account data should be managed in a central place.

• As identity is centrally managed, I don't want to have a "Remove user" button in the admin settings because all account data should be managed in a central place.

Value

• add capability graph.change_password_self in oCIS and reva to show/hide the "Change password" button

Michael Barz commented: Backend part will be part of ocis 3.0.0 in https://github.com/owncloud/enterprise/issues/5715

So the web improvement should go into stable-7.0
