authentification for differents groups FORM or BASIC

[zze-messager FTM balr002]

Hello, 


I have to do protect the accesses to my application in fuction of groups of
users.
For exemple, the group1 can access to the application if the url likes this
: 
/sc?AI=A*
/sc?AI=M*
/sc?AI=D

And the group2 can access with a url likes : /sc?AI=V*

How to do that with a FORM or a BASIC authentification ?
