We are facing the issue to migrate from Custom Authentication Service rule to SAML 2.0 rule. Because in the previous rule, we can customize the Authentication process but in Saml 2.0, we are unable to do.
In the LDAP AD, we have 2 types of user for example Employee ID specific and LAN ID specific. So in the Custom Authentication Service rule we have added the custom activity to pass the dynamic user based on some external table logic of either Emp ID or LAN ID. But in saml rule we can pass only either Name Identifier or Attribute on Operator Identification section which is coming from Active directory. Here they will send only Emp id so we have to hit external table and pass the dynamic user based on the existing logic but we are unable customize the SAML 2.0 rule because ther is no option. Can you please suggest how to handle this situation.
