Hi sweetblood,

Tanks a lot for your help!

I used your idea in the following code:

if( /cn=/ )
{
$result = $_;
$result =~ s/^cn=([^,]*?),//;
}
return $result

in this case your REGEX is returning cn=groups,dc=mp,dc=rj,dc=gov,dc=br

I need the opposite result.

I think a REGEX where in the first time remove the string cn=
so the result string will be portal.090710.191533.428571000,cn=groups,dc=mp,dc=rj,dc=gov,dc=br


The second REGEX will remove the entire string cn=groups,dc=mp,dc=rj,dc=gov,dc=br


To be lefting only the needed string portal.090710.191533.428571000

Can you help me?
Regards
Pierre
