why 'require' doesn't accept primary group

Hi,

I having trouble allocating primary group into require field.

    <Directory "/here/there/">
          Options Indexes FollowSymLinks
          AllowOverride All
          Order allow,deny
          Allow from all
          AuthType VAS
          #AuthVasRemoteUserMap ldap-attr sAMAccountName
          #AuthVasLocalizeRemoteUser on
          Require unix-group king
             </Directory>

My id:
uid=1230(superman) gid=1231(king) groups=,12674(admin),12885(test),1231(king),2312(popeye)

My web allows me to access to secondary (example test) group but not primary (king) group. My user group sometimes reach more that 12 secondary groups. When I set the require group to 'king' it give access denied ...
...."does not meet the 'require'ments to be allowed access"

please recommend a solution or workaround for this.
