JSI Tip 9882. How can I retrieve the distinguishedName of the logged on user, using standard commands?

I have scripted uDN.bat to retrieve the distinguishedName of the logged on user.

The syntax for using uDN.bat is:

call uDN DN

Where DN is a call directed environment variable that will contain the logged on user's distinguishedName, like "CN=Jerold Schulman,CN=Users,DC=JSIINC,DC=COM".

uDN.bat contains:

@echo off
if \{%1\}==\{\} @echo Syntax: uDN DN&goto :EOF
if exist "%TEMP%\uDN.VBS" goto getDN
@echo.Set objSysInfo = CreateObject("ADSystemInfo")>"%TEMP%\uDN.VBS"
@echo.sUser = 
" ^& objSysInfo.UserName ^& 
">>"%TEMP%\uDN.VBS"
@echo.WScript.Echo sUser>>"%TEMP%\uDN.VBS"
:getDN
for /f "Tokens=*" %%u in ('cscript //nologo "%TEMP%\uDN.VBS"') do (
 set %1=%%u
)
