WEBDAV

I have setup WebDav on AIX.

I am struggling however with permissions on the Directory.

<Directory "/usr/test/">
Dav On
Options Indexes FollowSymLinks
AllowOverride None
LdapConfigFile /usr/IBMIHS/conf/ldap.prop
AuthType Basic
AuthName DAV
<Limit POST PUT DELETE COPY MOVE MKCOL GET>
Require valid-user
LDAPRequire filter
"((groupMembership=cn=DEV,ou=EPUK,ou=P,ou=PCM,o=PUKNET))"
</Limit>
</Directory>

<Directory "/usr/test/concept">
LdapConfigFile /usr/IBMIHS/conf/ldap.prop
<Limit POST PUT DELETE COPY MOVE MKCOL>
Require valid-user
LDAPRequire filter "(|(groupMembership=cn=AAT,ou=EPUK,ou=P,ou=PCM,
o=PUKNET)(groupMembership=cn=DEV,ou=EPUK,ou=P,ou=PCM,o=PUKNET))"
</Limit>

This works fine - eveybody is Limited by the spesified directives except
AAT and DEV group.
I need to configure another group BBT for the same directory but with only
" read " permissions they should not be able to open any files.
Does this make sense ? Hope so.
Any Ideas?
