Access denied for user ABC on port 5986-> 'soap/rpc' from MWS


I am fetching data from IS to a portlet page.

I get this error as Failed to evaluate binding expression. and I traced in the server log in IS and got this error

“Access denied for user ABC on port 8954 -> ‘soap/rpc’ from MWS”

What might be the possible problem for this.

Please help me out with this. Is this issue related to Central users? If so, how can I configure Central users.



Is this issue got resolved … ?

I think the problem might be with SAML file.
