[SCM] Samba Shared Repository - branch master updated

Jeremy Allison jra at samba.org
Wed Oct 20 10:03:01 MDT 2010


The branch, master has been updated
       via  e1cfca1 Make getpwnam_alloc() static to lib/username.c, and ensure all username lookups go through Get_Pwnam_alloc(), which is the correct wrapper function. We were using it *some* of the time anyway, so this just makes us properly consistent.
      from  ab01d61 nsstest: no need for two copies of the same tool.

commit e1cfca1e2e0f005ac9d73c6b0eb64bc99413aec6
Author: Jeremy Allison <jra at samba.org>

    Make getpwnam_alloc() static to lib/username.c, and ensure all username lookups go
    through Get_Pwnam_alloc(), which is the correct wrapper function. We were using
    it *some* of the time anyway, so this just makes us properly consistent.
