37 91 Jun o Changes to Mark's code made by Bob Billson
|
|
|
38 <uunet!kc2wz!bob> are indicated by 'REB'
|
|
|
39
|
|
|
40 ?? ??? ?? o Further changes made by Charles Ownes
|
|
|
41 <trystro!czos9!chuck> to make it work more happily
|
|
|
42 with Rick Adams' UUCP are indicated by 'CNO'.
|
|
|
43
|
|
|
44 HINT: If you edit /dd/sys/password by hand, be sure you don't
|
|
|
45 add any extra carrige returns at the end of the file.
|
|
|
46 Each line should end with one carrige return. There
|
|
|
47 should be no blank lines between entries. If this
|
|
|
48 format is not adhered to, ADDUSER will not work
|
|
|
49 properly. -- CNO
|
|
|
50
|
|
|
51 92 Oct 20 o Minor additions to allow compiling with the makefile in
|
|
|
52 Rick Adams' UUCP.
|
|
|
53 o Improved the way chk_uid() picks its own user id.
|
|
|
54 o get_entries() now detects and reports blank lines in the
|
|
|
55 password file.
|
|
|
56 o User's login file script can now be customized. -- REB
|
|
|
57
|
|
|
58 93 Feb 14 o User name can now be given on the command line -- REB
|
|
|
59
|
|
|
60 93 Sep 4 o Special processing for user named 'daemon' --REB
|
|
|
61
|
|
|
62 94 Mar 30 o Added -s option for super user, fixed for OSK -- BGP
