SharePoint: People Picker and Disabled Users

I’ve already written a few things on this topic, but I thought I’d add additional background, consolidate concepts, and highlight a new (to me) twist. Background: SharePoint Server (doesn’t matter which version) People Picker should not return disabled user accounts from Active Directory. If it does, there’s a configuration problem in either Active Directory or

Test-SPContentDatabase throws authentication mode error

  Consider the following scenario: You move a content database from a Windows-claims web app to a new claims-based web application in a SharePoint 2016 or 2019 farm. You run Test-SPContentDatabase against the database. Example: Test-SPContentDatabase -Name Contoso_Content -WebApplication “” The output contains this warning: “The [] web application is configured with claims authentication mode

SharePoint – Intermittent error: “Sorry, this site hasn’t been shared with you”

Consider the following scenario: Randomly, when a user browses to a resource (site, list, etc) that they are supposed to have access to, they receive “Sorry, this site hasn’t been shared with you” (access denied).

SharePoint: Common NTLM Authentication Issues, aka: Consider Ditching NTLM

Update 1/26/21: Added Issue #7 NTLM authentication is not great. It’s not the fastest. In most cases, that honor would go to Kerberos. It’s not the most secure. Again, Kerberos. It’s not all that flexible. For example, it doesn’t work well for extranets or anything cross-firewall. In those scenarios, Trusted Provider auth (SAML / WS-Fed)

SharePoint: Another Reason User Profiles are not Imported

This is kind of a “fringe” case, but since it may not be the last time it happens, here’s a post: Consider the following scenario: In SharePoint 2013+ you’re using Active Directory Import to import user profiles as trusted provider-type (SAML) profiles. You find that profiles for some users are not imported. You have already
