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. If the hashed passwords compare, the access is permitted.
