The Ops Manager authentification process through SAML requires that the user's groups are specified in a dedicated SAML attribute sent by the IDP, so the user can connect to Ops Manager.

For this need, our IDP can only provide a field that contains free text. This field can contain many information, and can include special characters. We can add the Ops Manager groups in this field, among the existing text information.

However we need Ops Manager to parse this free field and get the groups information, which is not possible for now.

That's why we would like the implementation of regexp, or another solution, in OpsManager, so it can find the user's groups information in a "SAML Group Member Attribute" field containing many other information.
