You can use the Grant-SRDelegation cmdlet. This command allows you to set specific users in server-to-server, cluster-to-cluster, and stretch cluster replication scenarios. The command delegates the permissions to create, modify, or remove replication, without being a member of the local administrators group. For example:
Grant-SRDelegation -UserName contso\ onywang
The cmdlet reminds you that the user needs to sign out and then sign in to the server they're planning to administer in order for the change to take effect. You can use Get-SRDelegation and Revoke-SRDelegation to further control delegation.
