How to get read AD groups in applescript

Hi.

I'm trying to make a login applescript that work out if the current user is a member of an AD group.

I can get the username, but need to prepend it with "domain\"

I can do it with a shell script like this

export user=$(whoami) -- get the username

domain_user=$our_domain_name'\'$user -- prepend the domain and slash

dsmemberutil flushcache -- flush the cache

export answer="$(dsmemberutil checkmembership -U $domain_user -G group_name)"

if [[ "$answer" == *not* ]]

then

do some stuff here

fi

Ive tried putting this into applescript:

try

set user to do shell script "whoami"

set TheCommand to "dsmemberutil checkmembership -U " & "our_domain_name\\" & user & " -G group_name"

do shell script "dsmemberutil flushcache"

try

set Answer to do shell scriptTheCommand

end try

end try

But the shell command does not see the \. how can i get around the escape charater problem? The double slash does not work....

any clues?
