Roland,
If you're looking for the equivalent of apache's "basic" auth functionality, you'll want to use/configure the AOLserver nsperm module. Configuration consists of:
adding files to <server_root>/modules/nsperm:
group
passwd
perms
and adding to your service's startup config.tcl:
ns_section ns/server/${server}/modules
ns_param nsperm ${bindir}/nsperm.so
Check aolserver.com for additional info.
