There are a few different plugins winbind can use to perform the uid<->sid 
mapping. By default samba uses the tdb mapper which, as you describe, will 
generate uid maps on the fly. In my environment we have uid/gid info populated 
in active directory so our samba server is able to use the idmap_ad or 
idmap_adex modules to lookup uid info from ad. Depending on your environment 
you may be able to use the idmap_nss or idmap_ldap modules. See the idmap man 
pages on http://us6.samba.org/samba/docs/man/manpages-3/
