End Users Cannot See Managed Metadata Column Values – SharePoint 2010

The other day I encountered a weird error where no end users could see metadata field values in columns that were filled in throughout the site.

I thought I was going crazy because I could see them yet nobody else could. I knew it was a permissions issue and checked permissions on the Managed Metadata service app but that wasn’t it. I had no idea where else to look.

After doing some research, I came across this link:

Phew, thanks Jess Collicot.

According to Jess, the TaxonomyHiddenList (/Lists/TaxonomyHiddenList/) is used to cache terms and keywords for fast retrieval. The NT Authority/Authenticated Users group should have “read” permissions on this list.

Making the change worked instantaneously. Now I just need to find out how the NT Authority/Authenicated Users group got removed in the first place!
