    Abstract: A system and method for allowing roaming of a subscriber and password authentication a non-LDAP region. A user signs onto a network access server which in turn connects to the regional LDAP RADIUS server. Password authentication occurs by hashing a transmitted password and comparing it to a clear text password from an LDAP database that has been hashed in the same manner as the transmitted password. When the subscriber is in a non-LDAP region, The password proceeds trough a proxy server to a regional RADIUS server which connects to a non-LDAP server. The non-LDAP server connects to and SMS database and retrieve the clear text password associated with the non-LDFSAP user, hashes it according the same method as the transmitted hashed password and formats the password for comparison in the regional RADIUS server.
