Bug 707282

This is a regression that was introduced when we added the obfuscated password support. Previously, there was only one option, so it was an assumed default (mostly by accident, but we have to support that).

This makes it a regression that it is no longer the default. Customers are seeing this issue in production, so I'm proposing it as Urgent.

    New Contents:
Cause: SSSD incorrectly assumed that if "ldap_default_authtok" is used, "ldap_default_authtok_type" is set to "password" even if it was not explicitly specified in the config file. This assumption happened mostly because "password" was the only allowed value for some time. Later, when support for obcuscated passwords was added, this assumption was no longer true.
Consequence: Users who used ldap_default_authtok with no explicit ldap_default_authtok_type were experiencing a regression.
Fix: because ldap_default_authtok with no  dap_default_authtok_type set worked in the previous versions (even though by accident only), we made "password"
the default for "ldap_default_authtok_type"
Result: Configurations that don't specify explicit ldap_default_authtok_type behave as if it was set to "password"
