I am trying to create the MySites on our development instance using my production domain login. I can login to the root site, and my name is rendered correctly in the drop down, but when I try to create the MySite, I am getting a user not found error. I am able to create a MySite using a dev domain account, but cannot use my production domain account. Does anyone know what security configuration needs to occur so that I can use my production account?

The ULS log has this entry, which indicates I should be able to create the site:

But the actual site instantiation fails with this error:

Hi Susan,

As my understanding, your development and production environments are two (two way) trusted domains in one forest, and the SharePoint instance was built on the development domain. If this is the truth, please first verify whether your production domain account profile has been imported into the user profile service application. If it is not, refer to the following article to check the configuration of your user profile synchronization.
https://technet.microsoft.com/en-us/library/ee721049.aspx

If your user profile can be searched correctly, the issue might be caused by fact that the people picker search was limited to the development domain. Please use the following command to configure the people picker search domains:
stsadm o setproperty pn peoplepicker-searchadforests pv <list of forests or domains> -url <WebApp>

More information can be found in https://technet.microsoft.com/en-us/library/cc263460.aspx

Thanks,
