authentication: different groups for subfolders

[lisnatat]

how can i make subfolders accessible for other goups?

 

expampe:

[pre]

www

|-- folderA

|-- folderB

[/pre]

 

I have a group supergroup in which you have to access www and all it subfolders. this works quiet well:

[pre]

#/var/www/.htaccess

AuthType Basic

AuthName "Server"

AuthUserFile /var/www/.htpasswd

AuthGroupFile /var/www/.htgroup

Require group supergroup

[/pre]

 

now i all users of groupA to only have access to folderA. i tried this ...

[pre]

#/var/www/folderA/.htaccess

Require group groupA

[/pre]

... but it didn't work

 

any ideas?
