During the login procedure, BMC Helix Single Sign-On checks that the login ID provided by an end user matches the userID available in the user store of an identity provider (IdP). In many use cases, the login ID and the userID do not match, and end users cannot login by using their login credentials.
In such cases, transform the userID as required for an authentication method by specifying a userID transformation type.
Suppose you have a user name coming from the identity provider response and a user name specified in the Remedy AR System is CustomUserName. To configure the authentication method for end users' login, you need to transform the userID to remove the domain from the userID.
You might also need to transform a userID when you integrate BMC Helix SSO with BMC applications, set up an authentication method, and then change the original authentication method. The new authentication method might not provide the same userID format that was available with the original method, and you need to specify a userID transformation type for this authentication type.
