Webtop with portal access and saml resources

For anyone who comes across this post here was the reason for the issue and the work around provided by support.

https://support.f5.com/csp/article/K15387

"MRHSHint: Cookie is used for Microsoft SharePoint or for IBM Lotus Domino iNotes. MRHSHint cookie is used to carry information for SharePoint ActiveX controls."

To workaround this issue, implement the following iRule on the APM virtual server:

when HTTP_REQUEST { if { [HTTP::uri] contains "/saml/idp/res?id=" && [HTTP::cookie exists "MRHSHint"] } { log local0. "Removed MRHSHint cookie from request URI [HTTP::uri]" HTTP::cookie remove "MRHSHint" } }
