Description

Adds new Access Control Entry (ACE) to a certificate template Access Control List (ACL).

This command only prepares new certificate template ACL object. In order to write it to the actual object in Active Directory use this command's result to Set-CertificateTemplateAcl cmdlet (see Examples section).

Notes

Examples

Example 1

PS C:\> Get-CertificateTemplate -Name WebServer | Get-CertificateTemplateAcl | Add-CertificateTemplateAcl -Identity "Web Servers Global" -AccessType Allow -AccessMask Read, Enroll | Set-CertificateTemplateAcl

This commands adds 'Web Servers Global' global security group to the certificate template 'WebServers' and grants Read and Enroll permissions. After that, a new ACL is written to the actual object.

Example 2

PS C:\> $SourceACL = Get-CertificateTemplate -Name "WebServer" | Get-CertificateTemplateAcl
PS C:\> $DestinationACL = Get-CertificateTemplate -Name "WebServerV2" | Get-CertificateTemplateAcl | Remove-CertificateTemplateAcl -Force
PS C:\> $DestinationACL | Add-CertificateTemplateAcl -AccessRule $SourceACL.Access | Set-CertificateTemplateAcl

This example shows techniques used to copy and replace ACL from source certificate template to destination certificate template. a) First line retrieves ACL from source certificate template with common name "WebServer". b) Second line retrieves existing ACL from destination certificate template and clears all Access Control Entries (ACE). c) Third line copies ACEs from source certificate template to destination certificate template.
