pam_smb_passwd(7) or smbadm(8) or something should provide examples of smb setup for workgroups
We have no real examples or easy to follow steps to bring up SMB a smb server in a workgroup environment, especially if you don't already have some familiarity with what we need.
A good first step would be examples of the PAM configuration, etc, in a manual page that we can reference, even if it may not be easy to find itself.

For an example, see the equivalent kerberos stuff in pam_krb5(7) and a comment in the default pam.conf
# # Support for Kerberos V5 authentication and example configurations can # be found in the pam_krb5(7) man page under the "EXAMPLES" section. #
