To disable LDAP Settings:
  1. Go to Core > Settings > Security
  2. Select LDAP Authentication
  3. To disable certain roles, first remove the LDAP SB text in the field corresponding to the role
  4. Next Unmark the role
  5. Select Save & Exit
Once a user is no longer associated with the LDAP server, their cached password becomes their permanent password and is managed within Core.

When going into a User Profile, the Sign-in Information will display the ability to Set Temp Password.
