This commit is number 2 of 4.
In particular this commit focuses on: The guts of the moving about inside passdb. While these changes have been mildly tested, and are pretty small, any assistance in this is appreciated. ---- These changes allow for the introduction of a large dose of 'const' to the Samba tree. There are a number of good reasons to do this: - I want to allow the SAM_ACCOUNT structure to move from wasteful pstrings and fstrings to allocated strings. We can't do that if people are modifying these outputs, as they may well make assumptions about getting pstrings and fstrings - I want --with-pam_smbpass to compile with a slightly sane volume of warnings, currently its pretty bad, even in 2.2 where is compiles at all. - Tridge assures me that he no longer opposes 'const religion' based on the ability to #define const the problem away. - Changed Get_Pwnam(x,y) into two variants (so that the const parameter can work correctly): - Get_Pwnam(const x) and Get_Pwnam_Modify(x). - Reworked smbd/chgpasswd.c to work with these mods, passing around a 'struct passwd' rather than the modified username passdb/ - Kill off disp_info stuff, it isn't used any more - Kill off support for writing to the old smbpasswd format, it isn't relevent to Samba 3.0 - Move around and modify the pdb_...() helper functions, adding one that sets the last changed time to 'now' and that sets the must change time appropriately. - Remove the ugly forced update of the LCT- value in pdb_smbpasswd. - Remove the implicit modification of the ACB flags when both NT and LM passwords are set. - Removed substation in pdb_getsampwnam output, as a single password change will render them inoperable in any case (they will be substituted and stored) - Added a default RID to the init_sam_from_pw() function, based on our rid algorithm. - Added checks that an smbpasswd stored user has a uid-based RID. - Fail to store tdb based users without a RID lib/ - Change the substituion code to use global_myname if there is no connection (and therefore no called name) at the present time. (This used to be commit 8f607810eb24ed1157bbd2e896c2c167bc34d986)
