How to use a variable as Ldapfilter

Hi,
I have a list of email addresses for which i need to find the associated
samaccountname in AD.
the email addresses are standard (first.last@xxxxxx)
Here is the script i use (with Quest extensions)

$addresses = Get-Content c:\emaillist.txt

Foreach ($mad in $addresses)
{
$lfilter = "'(mail=$mad)'"

$user = Get-QADUser -LdapFilter $lfilter

$user
}

for user first.last@xxxxxx
$lfilter would return '(mail=first.last@xxxxxx)'

When used as a variable, it won't return anything. However if i make a
manual Get-qaduser -ldapfilter and add the $lfilter content to it, it returns
the value. Can somebody tell me what i am doing wrong or if there is a better
solution for this ?
thanks in advance
Bruno

I'm not using Quest Extensions so I can not test, but just from a formal
perspective I assume that the extra single quotes in $lfilter are wrong. Try

$lfilter = "(mail=$mad)"

Hi Gerd, thanks for the prompt answer.

You were right, it works fine now !

I thought i had to put both as the ldapfilter requests usually '(xyz)' format.
I will check that to avoid further mistakes...
