- Crack '98 sets the connection to 0 for supervisor,
- and then creates a user object in the bindery which must
- have an equivalent property. Then it adds supervisor
- equivalent to the supervisor equivalence property so it
- can make an account equivalent to that of supervisor. It
- supports Novell NetWare 2.x, 3.x, 4.x, and Novell IntraNet
- Ware 4.x. This is what the account's login script should
- look like after you've run the program.

- Here, the SUPERVISOR default logins are the
- directory names SYS:SYSTEM and/or SYS:PUBLIC as the
- filename NET$LOG.DAT. NetWare assigns each user or
- group a unique number when it is defined. The
- SUPERVISOR user number is always 1. All other users and
- groups are assigned hexadecimal numbers. Since all mail
- directories are created in the directory SYS:MAIL, the
- LAN SUPERVISOR's mail directory is SYS:MAIL\1. The user
- login script itself, however, is stored in a file named
- LOGIN with no extension. For example, IL\1\LOGIN. The
- user login script is used to define user-specific
- resources and environment settings. If a user login
- script file exists it will be executed. If it does not
- exist, then the LOGIN program invokes a default user
- login script. This can be a source of trouble, as the
- default user login script might interfere with drive
- mappings in the system login script.
- There are two utilities provided with NetWare to
- create new user accounts. These are SYSCON and
- MAKEUSER. Both are displayed as options on the NetWare
- Login main screen, and can be used to create a new
- account, and its corresponding login script.
- When a user logs into the NetWare, the LOGIN
- program verifies if the entered password specifies the
- id that corresponds with it, and then retrieves the user
- rights information from the file server. If one exists,
- the system login script is then executed. This script,
- is then stored in the user acount's mail directory. In
- NetWare 2.x, the password file is NET$BVAL.SYS, and is
- kept in the SYS:PASSWD directory along with the security
- file NET$BIND.SYS. In 3.x, the password file is
- NET$VAL.SYS and is also kept in the SYS:PASSWD directory
- along with the security files NET$OBJ.SYS and
- NET$PROP.SYS. In 4.x you have PARTITIO.NDS, BLOCK.NDS,
- ENTRY.NDS, VALUE.NDS, and UNINSTAL.NDS. The system
- login script is created with the SYSCON utility be the
- LAN supervisor and is stored in a file named NET$LOG.DAT
- in the SYS:PUBLIC directory. Here is an example of how
- permissions are assigned.
-
- USER1 is a member of the groups EVERYONE and ACCOUNTING.
- All users are members of EVERYONE.
- Group EVERYONE has Read, Open, and Search rights in SYS:APPS.
- Group ACCOUNTING has Write, Create, and Delete rights in SYS:APPS\DATA
- USER1 has Parental and Modify rights in SYS:APPS\DATA\USER1
-
- USER1's trustee priveleges are accounted for as
-
- Directory Group Rights
- SYS:APPS EVERYONE [R O S ]
- SYS:APPS\DATA ACCOUNTING [ W CD ]
- Trustee priveleges [RWOCD S ]
-
- The one access type that gains everything is called
- Supervisory. Its environmetal settings are RWOCDPSM.
