I have a strange problem in SharePoint 2013 OnPrem.
SP used to be set up with AD import from two domains, let's call them DomainA and DomainB. Then it was decided to remove DomainB, and all users in it. The users of DomainB should no longer have access to SP, and should not appear in people picker controls or otherwise inside SP. What we did so far:
- Removed the AD import connection to DomainB
- Removed all the user profiles from DomainB from within Central Admin (manage user profiles)
- Did a full sync
- Removed all DomainB users from the user information list (the one at /_catalogs/users/simple.aspx) using powershell
- I even tried setting the Peoplepicker-onlysearchwithinsitecollection property using stsadm
But still, the DomainB users are showing up in people picker controls, e.g. when clicking "Share site" and searching for users.
I do not understand where this information is coming from. Any ideas?
