When you add users to the CASHostAccountRequired custom group, CAS session processes run under the end-user identity rather than the cas user. This behavior is known as "host launch." However, if you use a SAS^® 9.4 one-time password (OTP) for authentication, the host launch does not occur for these CASHostAccountRequired users. Instead, the session processes run under the cas identity.
