Hi Aaron,
Came across your post this morning as I have an issue using the saml2=disable parameter and /IRJ. Once SAML2 logon module is bypassed and the basic logon module presents the UserID/Password form, no credentials are accepted.
What other changes did you make (i.e., authentication scheme) to allow you to successfully bypass SAML2 and logon using UserID/Password?
Regards,
Dan
