Ad issues in SharePoint

Hello, I am Prosenjit an expert in AWS, Azure, VMware and multiple Microsoft technologies. I presume you are using samAccountName not userPrincipalName attribute. The 20 character limitation for samAccountName is a common restriction and this needs to be changed in Schema. So, the prerequisite is, you must have Schema Admin rights. Regarding the second issue, I need to review the script and may need to test it in my own LAB before I can propose a solution. Let's connect to discuss further. Best regards, Prosenjit SEN

I am using power shell and Linux kernel for a long and have good experience in system admin while working for user management and group categorisation. I think adding upn needs different set of commands and abilities which is a pipeline scopic management.

I have experience with user access management in AD and good experience with powershell automation. I think we can solve this with some further information about your setup and requirements.
