PR Summary

• Modification to Logic for User-LDAP Directory Binding
  The team has enhanced the way our software binds users to an LDAP directory. Previously, there may have been instances where a user was not always properly connected to the appropriate LDAP directory. This update ensures a user is correctly assigned by adding a 'rebind' mode. This acts as a double-check procedure, ensuring our app aligns with the user accounts as expected, enhancing the overall user experience.
