Description

Adds new Access Control Entry (ACE) to a Certification Authority's Access Control List (ACL).

Notes

Examples

Example 1

PS C:\> Get-CertificationAuthority "ca01.example.com" | Get-CertificationAuthorityAcl | Add-CertificationAuthorityAcl -Identity "Cert Managers" -AccessType "Allow" -AccessMask "ManageCertificates" | Set-CertificationAuthorityAcl -RestartCA

In this example, existing Access Control List (ACL) object is retrieved from CA server hosted on "ca01.example.com" and added new "Allow" Access Control Entry (ACE) for group "Cert Managers" with "ManageCertificates" access and writes new ACL back to CA server configuration. CA service is restarted to immediately apply changes.

Example 2

PS C:\> $SourceACL = Get-CertificationAuthority "ca01.example.com" | Get-CertificationAuthorityAcl
PS C:\> $DestinationACL = Get-CertificationAuthority "ca01.example.com" | Get-CertificationAuthorityAcl | Remove-CertificationAuthorityAcl -Force
PS C:\> $DestinationACL | Add-CertificationAuthorityAcl -AccessRule $SourceACL.Access | Set-CertificationAuthorityAcl -RestartCA

This example shows techniques used to copy and replace ACL from source CA to destination CA. a) First line retrieves ACL from source CA server hosted on "ca01.example.com". b) Second line retrieves existing ACL from destination CA server hosted on "ca02.example.com" and clears all Access Control Entries (ACE). c) Third line copies ACEs from source CA to destination CA. Destination CA service is restarted to immediately apply new ACL.
