The branch, master has been updated
via 2d22bbf s3-selftest Look only under source3 for smb.conf files
via ff9b668 s3-auth Rename user_session_key -> session_key to match auth_session_info
via 17d8f0a s3-auth use create_local_token() to transform server_info -> session_info
from 2ec4826 Move SET_STAT_INVALID call added by Volker as fix for bug 8042 - Newly create files are always failed with NT_STATUS_FILE_IS_A_DIRECTORY

commit 2d22bbf2c0af57c1bb7665590960a9b888ee8a4d

s3-selftest Look only under source3 for smb.conf files
This test looks for any .conf file with [global] in it, and assumes
it's a Samba3 format smb.conf file. If 'make test' has been run in
the top level build, it was finding the smb.conf files it generated.

s3-auth Rename user_session_key -> session_key to match auth_session_info
commit 17d8f0ad30847bb940f645ee1817d782ddaaee74
Author: Andrew Bartlett <abartlet at samba.org>
Date: Fri Feb 11 11:50:37 2011 +1100
s3-auth use create_local_token() to transform server_info -> session_info
Before a auth_serversupplied_info struct can be used for
authorization, the local groups and privileges must be calculated.
create_local_token() now copies the server_info, and then sets the
calulated token and unix groups.
Soon, it will also transform the result into an expanded struct
auth_session_info. Until then, the variable name (server_info vs
session_info provides a clue to the developer about what information
has been entered in the structure).
By moving the calls to create_local_token within the codebase, we
remove duplication, and ensure that the session key (where modified)
is consistently copied into the new structure.
