Powershell-将Active Directory用户名与电子邮件地址进行比较

Question

I am currently trying to find all AD users that have been created using the model "firstname@domain.com" versus our new standard of "FirstInitialLastName@domain.com". I'm using the Quest ActiveRoles modules, specifically Get-QADUser to pull down my user details:

Get-QADUser -enabled -IncludedProperties PrimarySMTPAddress | ?{$_.Type -match "User"} | Select-Object FirstName,PrimarySMTPAddress ...

That gets me a list of user first names and their SMTP address. Where I am stumped is how to compare the results.

I thought normalizing the values (either adding "@domain.com" to the first name string or stripping "@domain.com" from the SMTP string) and then doing a -ieq test would be the best approach. I have found I can do the first with:

%{ $address=$($_.FirstName + "@domain.com";) }

But I can't figure out how to then test $address against the PrimarySMTPAddress string. I can create a second variable with:

%{ $smtp=$($_.PrimarySMTPAddress); }

and get the result:

[PS] C:\>$addy -ieq $smtp
True

I'm just unclear how to do it all in stream so that I can process my tree at once. If this is something that's just more suited to a script than a single line, that's fine too. Coming from the glorious world of BASH my brain just wanted to one-line it.

Answer 1

Get-QADUser -Enabled -Email * -SizeLimit 0 | 
Where-Object {$_.Email.Split('@')[0] -eq $_.FirstName }

Answer 2

Try this:

Get-QADUser -enable -IncludedProperties PrimarySMTPAddress |
? { $_.PrimarySMTPAddress -match ("^"+[regex]::escape("$($_.firstname)")+"@domain.com") }
