hi all,
I'm trying to find how to determine if a property or attribute exists in
an AD object. Specifically the accountexpirationdate. If I just look for and
it's not there, and exception is thrown.



Quick example:

$oUser = [adsi] "LDAP://CN=Joe User,OU=HisOU,DC=Domain,DC=World"
If ($oUser.ifAttributeexists($myAttribute)) {
do stuff
}

Is there a way to accomplish this?

Thanks.

Hi!

If using Quest`s Active Directory cmdlets are an option, you can accomplish
this by using this one-liner:
Get-QADUser | Where-Object {$_.accountexpires -ne $null}

You can get Quest`s AD cmlets from here:

Try:

[adsi]::Exists("LDAP://CN=Joe User,OU=HisOU,DC=Domain,DC=World")

nevermind, I just realized you were asking about the attribute and not the
object itself...guess I should slow down and read the entire thing next time

Thanks for trying Mike. I like the [adsi]::Exists though. How can I find out
what other methods are available through the [adsi] provider?

I think exists() is probably the only static method of any use, but you can
use get-member:

[adsi] | get-member -static

And for instance members:

$user = [adsi]"LDAP://CN=Joe User,OU=HisOU,DC=Domain,DC=World"
$user | get-member

The above will give you an adapted view, to view the raw object:

$user.psbase | get-member

This may be of some help:

The quest cmdlets are alot easier to work with and will save you some time
if you have the option to use them.
