LDAP Single Sign On Token is a SASL (Simple Authentication and Security Layer RFC 2222 [RFC2222]) mechanism to allow single sign-on to an LDAP Directory Server environment. Tokens generated by the LDAP server can be transmitted through other protocols and channels, allowing a broad range of clients and middleware to take advantage of single sign-on in environments where Kerberos v5 or other Single Sign On mechanisms may not be avaliable.
