help with variables in x500 Address...

Dec 8, 2014 at 10:19 AM
Hello,
i´m trying to change the proxyAddresses Attribute for all user within a OU. It works well but the Variables won´t work:

admodcmd -dn OU=test,OU=test,DC=domain,DC=test -custom proxyAddresses "X500:/O=EXCHANGE 01/OU=EXCHANGE ADMINISTRATIVE GROUP (XXXXXXXXXXXX)/CN=RECIPIENTS/CN=%´givenName´%.%´sn%"

I also tried:
admodcmd -dn OU=test,OU=test,DC=domain,DC=test -custom proxyAddresses "X500:/O=EXCHANGE 01/OU=EXCHANGE ADMINISTRATIVE GROUP (XXXXXXXXXXXX)/CN=RECIPIENTS/CN="%´givenName´%"."%´sn
%

Can anyone give me a hint if this could work or am I trying something impossible?
Thanks for helping
