I am currently trying to set up a duplicate SharePoint environment for testing service packs and other updates.
I have used a SQL backup and restore method of migrating the content databases as I have several times before without issue.
However, I am currently having an issue where the user site permissions such as their group membership is not being correctly transferred across. All the site content is provisioned correctly and it even shows the Users in the groups, however if I try to
access the site as that user they get an access denied error. If I re-add the user (I.E delete the name and give them permissions again) they have access, however their are currently 100s of user to add so it would not be a viable solution to do all of this
manually.
Both the original and the new duplicate farms are on the same domain and or otherwise identical in set up.
Has anyone else experienced this?
