samba - Feb 2005 - Corrupt Database and couldn't map SID.

I'm running Samba 3.0.11.  Compiled with:   

./configure '--with-ads' '--with-pam' '--with-winbind'
'--with-smbmount' '--with-shared-modules=idmap_rid'

It configured, make and make installed fine.  I configured the idmap_rid using
the following directives in the smb.conf.

;  IDMap Stuff
   idmap backend = idmap_rid:<DOMAINNAME>=500-100000000
   idmap uid = 500-100000000
   idmap gid = 500-100000000

;  Winbind Stuff
   winbind use default domain = yes
   winbind separator = +
   winbind enum users = no
   winbind enum groups = no
   winbind nested groups = yes
   template shell = /bin/bash
   obey pam restrictions = yes

Problem is after a few days I get error messages in log.winbind that say the
database is corrupt or it couldn't map the SID.

This is a kernel issue IIRC.  See

	https://bugzilla.samba.org/show_bug.cgi?id=1032

Try setting 'use mmap = no' as a temporary workaround.
