https://community.appian.com/discussions/f/general/14003/modify-group-membership-rulesI&#39;m implementing a SAML solution in which users from many different (not known) domains could request and be granted access to an Appian solution. The user receives an invitation to register with the AD - sent via an Appian integration.

Would that be sufficient for your use case?<br /> <br /> Otherwise, I&#39;m not aware of anyway to dynamically modify group rules except potentially through coding against the API. <br /> <br /> For your last point, take a look at the Personalization Utilities shared component. It has an alternate Create User smart service that allows you to supply a &quot;password&quot; (that would never be used for SAML users) - since the password is supplied, no email would go out.<div style="clear:both;"></div>
