After installation of SP1 of Sharepoint 2013 and KB2935257 on Microsoft Dyanmics AX 2012 R2 CU7 i got following error when i try to open the enterprise portal:

You cannot view data on this page because you are not a registered user in Microsoft Dynamics AX. Contact your Microsoft Dynamics AX administrator.

Unable to cast object of type 'System.Int32' to type 'System.String'.

at Microsoft.Dynamics.Framework.Portal.AxSharepointWebSession.OnLogon(IAxaptaAdapter axaptaAdapter)
at Microsoft.Dynamics.Framework.BusinessConnector.Session.DynamicsSession.Init(ICacheContext context)

I tried to reinstall the enterprise portal but i'm still getting this error. 

Please suggest what could be the cause for error message. 

Thx

    RE: Unable to cast object of type 'System.Int32' to type 'System.String'.

    I am also facing same issue and we are stuck here. I tried many things as per mentioned by people above, but no luck. I have installed an Hotfix KB2935257 and after that i started facing this issue. I was wondering can this hotfix cause this issue ?  Also i have standalone machine/server hosting AOS, Ax client and share point. I am facing this issue on this server.  Even i refresh the business connector config and ax client config but no luck. Can somebody give me any specific resolution for this issue? I wonder is it a known bug?

    Thanks

    Hi André,

    All users can connect to the client without any problems. We also have multiple domain names but we only use one domain. All users including the business connector proxy account (Made it a user in ax) where getting that message.

    Only one AX environment will be using that sharepoint server.

    I got the basic role center working now. Your user client comment gave me the idea to install a client on the same machine as sharepoint to check for connectivity issues. When I started ax the default role center popped up without the error message. I assume something has changed in the ax configuration on the server to make it work.

    Hi Koen,

    Can this user access the client without problems? Can you also indicate if this is an environment with multiple domain names which do have a trust?

    Do you have more than one AX environment running using the same Sharepoint server?

    Yes the site is registered under the websites in the sys admin module. I also tried to remove it and register again.

    Hi Koen,

    You need to register EP site inside Dynamics AX under Sys Admin module.

    Have you registered your EP site or not?

    Thanks,

    Baber.

    I am also facing the same problem but on AX 2012 R2 CU7 with Sharepoint 2010 sp2.

    When opening the enterprise portal I get the following message:

    4300.EPError.JPG

    To try and solve it I did the following steps:

    • Clean install of de ep 
    • Reinstall of the business connector on the aos service
    • Checking the Dynamics Ax Configuration (busniss connector config) on the sharepoint machine
    • Adding the businness connector proxy account to all security groups

    Does someone have any other suggestions on what I can try.

    Thanks!
