PowerShell : Converting AccountName to SID and vice versa
I did allready a lot of posts about using the system.security .NET class and methods,
But as I needed to lookup a SID from a security template at work today, and I was on a machine without my Custom Tabcompletion ( See PowerTab Overview Page ), so I had no Tab completion on .NET classes, it took some time to find the complete classname again and it is a lot of typing without tabcompletion.
Hence, as I need this often, I decided to make to simple utility functions for this, and load them in my profile :
function ConvertTo-NtAccount ($sid) {(new-object system.security.principal.securityidentifier($sid)).translate([system.security.principal.ntaccount])}
function ConvertTo-Sid ($NtAccount) {(new-object system.security.principal.NtAccount($NTaccount)).translate([system.security.principal.securityidentifier])}
now you can use them like this :
PoSH> ConvertTo-Sid everyone
BinaryLength AccountDomainSid Value
------------ ---------------- -----
12 S-1-1-0
PoSH> ConvertTo-NtAccount S-1-5-32-544
Value
-----
BUILTIN\Administrators
PoSH>
As said I did allready more posts about this topic
So for more information and more (advanced) examples about working with SID's Users and ACL's,
also see : Posts on my old blog about this . (about 18 posts where I use this class)
Enjoy,
