Hey @PeterPerera ,
From the documentation, it appears the process is working as expected.
Since Galleries with SAML or built-in authentication use e-mails as a form of ID and both allow user creation, I believe it is following the same steps erroneously. I guess you can add a random password since the authentication will happen on your SAML IdP.
Best,
