Any help would be appreciated on this issue.
SharePoint 2013 DEV environment
1 web, 1 app, 1 SQL servers sitting in DMZ FOREST - CALL IT DMZ1
User accounts are all in a separate forest - Let's just call it INTERNAL1
I have set up User Profile sync and this is working correctly, I am getting profiles from accounts in our internal domain. I specified an account from the forest root as my synch account, and this is working well. I can see various properties from AD. Good so far.
I have created a new web application for MySites called dev.mysites.company.com. This is also my MySite host. I have self site creation turned on. The permissions for this look right to allow anyone to create a new site.
I have had multiple users test this functionality and they are not able to create MySites. They get a message on the screen that there was an issue, and I get this message in the logs:
My Site creation failure for user 'domain\user' for site url 'http://dev.mysite.ddiworld.com/personal/user'.The exception was: Microsoft.Office.Server.UserProfiles.PersonalSiteCreateException: A failure was encountered while attempting to create the site. ---> Microsoft.SharePoint.SPException: User cannot be found.
Any thoughts on this would be greatly appreciated. Thank you in advance.
