winbind and NSS

[Arup Biswas]

I am interested in using winbind for mapping users and
groups across unix and windows domains.
To achieve this samba documentation specifies the
following entries in the nsswitch.conf

passwd: files(nis)	winbind
groups:  files(nis)	winbind

My understanding of the smbd code is that getpwnam()
is the only nss call that is really used in the
context of mapping users/groups. My question is what
is the basic minimal set of nss calls that I need to
support in order to achieve user/group mapping. 

Here is why I am considering supporting only the
minimal set of nss calls: we are using a platform
where nss is not supported and the less number of
calls we need to "nss-enable" the less work for us. We
can keep the other password/group access calls
nss-disabled.

Any pointer in this direction will be highly
appreciated.

Thanks in advance,
