Hi I want to set-up Single Sign On (SSO) solution on Redaht Linux. However, I have read many web site reference that use different application so I am confused which on can be used for SSO? Do I need configure all of them? Do I really need Kerberos 5? Do I still miss something? Is TLS/SSL nessary for SSO? Kerberos 5/Cyrus-sasl/Open LDAP/Berkeley DB/pam_ldap/nss_ldap Thanks Cody
