In systems with LDAP, changing the passwords for users in the OO interface is not always possible, as passwords are stored on the ldap system. Up until now, trying to change a password of such a ldap user results in an error message, informing that the new password couldn't be saved, with an unexpected error.
It would be helpful if the error message would provide more information as to why the password couldn't be saved, mentioning the ldap setting.
Of course, it would be even better to remove the Password-tab for LDAP user.
The inability to change passwords on such systems leads to a second problem, the "Forgot password" link on the login page. LDAP users will be unable to reset their password with that link. As OO systems with LDAP connection often also have regular users, just removing the link isn't always an option. The "Forgot password" wizard should therefore contain information about that particular problem, or even be able to identify ldap users as such and inform them that they cannot reset their password that easily.
