The LDAP Authentication works with Microsoft Active and other LDAP directories and thus eliminates the need for multiple passwords.
Of course Domino Directory Assistance already supports authentication against the Microsoft Active Directory (MSAD). However, MSAD authenticated users are then known to the Domino servers with their MSAD username, not their Domino username. Access rights will not work, as the MSAD username is generally a single text string and the Domino username is generally a full user name including first name, last name organizational units, organization and sometime even a country code.
Yes, "ADSync" supports synchronization of the MSAD and the Domino directory. However, companies tend to have strict policies for MSAD password expiration. Users therefore end up, at least temporarily, with several passwords.
SecureDomino R6 eliminates the need for multiple passwords. It supports authentication against MSAD or any other LDAP. Any LDAP search string can be used for authentication. SecureDomino then maps the LDAP search string to a Domino username and authenticates the user with their Domino username. Access rights in groups and ACL´s still work. And the second a password is updated in MSAD the same password works for Domino authentication as well.
