SharePoint: Domain Local groups from Trusted Forest are not valid

  Consider the following scenario: You have a SharePoint 20xx (doesn’t matter) site and have configured People Picker to search a trusted Active Directory Forest or Domain. You have a security group of type “domain local” in the trusted forest that has several users in it. You use People Picker to search for the group,

Kerberos – KRB_AP_ERR_MODIFIED is not always an SPN problem

TLDR: This can also be caused by a mismatch in security policy “Network Security: Configure encryption types allowed for Kerberos“.   Consider the following scenario: You have a web site set up to use Kerberos authentication. It doesn’t matter what kind of site, but we’ll say it’s a SharePoint site, since that’s the theme around

SharePoint – AD Import: Using PowerShell to create property mappings

First off, when using Active Directory Import in SharePoint 2013, 2016, and 2019, it’s completely normal to see very few (like 2) mapped properties in the User Profile Service Application (UPA) | Manage User Properties.

In that case, timer jobs with lock type “ContentDatabase” would not run because no server in the farm has its AllowContentDatabaseJobs property set to “true”.

SharePoint 2016 / 2019 – Timer jobs with ContentDatabase lock type do not run

In SharePoint 2016 and 2019, you may find that some timer jobs are not doing what they should. In timer job history, you may see that the timer jobs are running successfully, but they aren’t doing anything. Depending on the timer job, this can be a little difficult to detect.

SharePoint 2016 / 2019 / SE – Use PowerShell to Sync user data from UPA to sites

Some Background: Since pretty much the beginning of SharePoint, user profile synchronization has been a two-step process: 1. Import user data from Active Directory to the User Profile Service Application (UPA). 2. Push that user data from the UPA down to each site collection. Step 2 is our focus here, and is automatically done by
