I went to disable a user account today and on the admin page for users the operations column (which would have the edit option as i remember it) is missing (it was there yesterday when i disabled another user).

The only admin operations done yesterday were:
disable one user
remove a connection to a application on a host that no longer exists (secure/admin/ConfigureCrowdServer.jspa page)
change the account/password used for Delegated LDAP Authentication (I have reverted that and it made no difference)
Where has the option gone and how do i get it back?
