A couple functions I use to convert DN to Canonical, and canonical to DN. I find them handy for adhoc AD tasks… I saw someone ask about it on #powershell and figured I would share :)
- #Author: Glenn Sizemore glnsize@get-admin.com
- #
- #Purpose: Convert a DN to a conicalname, and back again.
- #
- #Example: PS > ConvertFrom-Canonical 'get-admin.local/test/test1/Sizemore, Glenn E'
- # CN=Sizemore\, Glenn E,OU=test1,OU=test,DC=getadmin,DC=local
- # PS > ConvertFrom-DN 'CN=Sizemore\, Glenn E,OU=test1,OU=test,DC=getadmin,DC=local'
- # get-admin.local/test/test1/Sizemore, Glenn E
- function ConvertFrom-DN
- {
- param([string]$DN=(Throw '$DN is required!'))
- foreach ( $item in ($DN.replace('\,','~').split(",")))
- {
- switch -regex ($item.TrimStart().Substring(0,3))
- {
- "CN=" {$CN = '/' + $item.replace("CN=","");continue}
- "OU=" {$ou += ,$item.replace("OU=","");$ou += '/';continue}
- "DC=" {$DC += $item.replace("DC=","");$DC += '.';continue}
- }
- }
- $canoincal = $dc.Substring(0,$dc.length - 1)
- for ($i = $ou.count;$i -ge 0;$i -- ){$canoincal += $ou[$i]}
- $canoincal += $cn.ToString().replace('~',',')
- return $canoincal
- }
- function ConvertFrom-Canonical
- {
- param([string]$canoincal=(trow '$Canonical is required!'))
- $obj = $canoincal.Replace(',','\,').Split('/')
- [string]$DN = "CN=" + $obj[$obj.count - 1]
- for ($i = $obj.count - 2;$i -ge 1;$i--){$DN += ",OU=" + $obj[$i]}
- $obj[0].split(".") | ForEach-Object { $DN += ",DC=" + $_}
- return $dn
- }
