How to check an AD group is Unix-Enabled with Powershell

06 April,2021 by Rambler

A common requirement when using Active Directory Groups and Linux is to check if the Active Directory Group is Unix enabled. In simple terms - Unix - enabling means to provide a group (or user) a Unix identity. 

Importantly - Unix logons are identified in the system by an  identifier. Sometimes you make a request to Unix enable an AD group and need to check if the group has actually been Unix - enabled. 

When querying the Active Directory and to identify if an AD group has been Unix -enabled ,  the key is to resolve the AD group and the gidnumber . If there is no gidnumber associated with the  group  than the account is not Unix-enabled. The Gidnumber (aka Group Identifier)  is used within Unix ,POSIX & Linux , when multiple users are put into groups. 

Here is a Powershell statement using the Get-ADGroup cmdlet. If there is no gidnumber than the AD group is not Unix-enabled. 


Get-ADGroup -Filter "name -like 'myADgroup'" -Properties * | select name,gidNumber
