Description

After deactivating Enable User Synchronization in Administration area and saving changes without providing the Bind Password for the LDAP connection (see the blue boxes), user login is no more possible. Saving again with provided password re-enables users to login to the website.

Bind password is needed for this auth source to work if your server does not allow anonymous connections

The Problem is that on every change on the site the "Bind Password" must be refilled. If the field is blank and for example the option "Enable User Synchronization" will be deactivated this auth source doesn't work. After refill the password and save the site without any modification the auth source will work as normal.
Is it a security feature that the bind password must be refilled on every change on the site or is this a bug?

yes bind password if it was set should be shown here
