Hi, I just pushed pysaml2 PR #613 to enable more flexible entity catetory support: https://github.com/IdentityPython/pysaml2/pull/613 Before this PR entity category modules to be used to help configure attribute release for an IdP could only be imported from the name space saml2.entity_category. This is cumbersome and made overlaying new entity category modules or custom versions of existing entity category modules difficult. With this PR entity category modules are first searched for on the general module import path. If they are not found there then the current default of importing from saml2.entity_category.<module> is used. Thanks, Scott K
