SPD Server
user data is maintained in an internal SPD Server password table.
Each record in the password table describes the specific attributes
and capabilities that are associated with an individual user. SPD
Server uses two types of user authentication. The first type of user
authentication is LDAP (Lightweight Directory Access Protocol). The
second type of user authentication is traditional authentication,
which SPD Server performs internally. LDAP authentication is performed
by an LDAP server that runs on the SPD Server host machine. The section,
LDAP Authentication Notes, contains more details on using LDAP with SPD Server.
