Citrix access using SAML

So Azure AD is your SAML IdP and the F5 is your SAML SP and you want the Citrix Storefront to be another SAML SP of Azure AD?

If the F5 and Citrix are SP on the same SAML IdP Azure AD this should work but if you want the F5 to use username/password for SSO then reserch how Azure AD can return the SAML username and password to to the F5 SAML SP as saml attributes in the assertion so it can use it to SSO in the Citrix if that is possible.  Still I do not know if the userame and password can be inserted by the Azure AD as F5 IdP supports this but for Azure you have to check.
