Enterprise portal add user or group from other trusted domain

I've been dealing with enterprise portal but using cross domain trust when accessing the enterprise portal website. When adding I tried to add users from other trusted domain the Sharepoint didn't recognize the user I tried to add.

To be able to add other trusted domain you can use below Sharepoint powershell:

STSADM.exe -o setproperty -pn peoplepicker-searchadforests -pv domain:"trustedDomain" -url "http://WebApp/"

After execute the powershell script you will be able to add other domain trusted.

Enterprise portal error in Dynamics AX 2012 R3

Below error was a common error that can happen in Dynamics AX 2012 R3 EP, sometimes we hardly know what was missing or not configured properly:

• You cannot view data on this page because you are not a registered user in Microsoft Dynamics AX. Contact your Microsoft Dynamics AX administrator.
• No .NET Business Connector session could be found.

Here are some point that you might need to check

• Make sure the necessary inbound services was running
• Make sure BC connector been configured properly

Action that you might try:

• Re-create the AX user account (delete and import again the AX users)
• Delete and register/add again the EP website manually (System administration - Setup - Enterprise portal - Web site) [this one will always works for me for the 1st error point]
