.B3
1.0 <SUMMARY
.B1
^THIS IS A MAINTENANCE RELEASE OF <LOGIN. ^MOST
OF THE EDITS ARE BUG FIXES WHICH WILL INCREASE ^^LOGIN\\'S STABILITY
IN THE FIELD. ^ALSO INCLUDED IS (UNSUPPORTED) CODE TO ALLOW THE USER
TO CHANGE HIS/HER OWN PASSWORD AND A SYSTEM FOR ENCRYPTING PASSWORDS
FOR GREATER SECURITY.
.B1
^^LOGIN\\ IS DOCUMENTED IN ^SOFTWARE ^NOTEBOOOK ^VOL. 2^A.
.B1
^THIS VERSION OF ^^LOGIN\\ SUPERSEDES ALL PREVIOUS VERSIONS.
^IT RUNS UNDER ALL SUPPORTED MONITORS.
^^LOGIN\\ ^V60 HAS BEEN TESTED SUCCESSFULLY UNDER
5.07^B/6.01^B, 6.02, 6.02^A, AND FIELD TEST VERSIONS OF 6.03.
.B1
^THE FOLLOWING ^^CUSP\\S MUST BE USED WITH ^^LOGIN\\ ^V60:
.B1.I5
^^MACRO\\ VERSION 50 OR 52
.I5
^^SCAN\\ AND ^^WILD\\ VERSION 7
.I5
^^FACTOR\\ VERSION 1
.B3
2.0 <EXTERNAL <CHANGES
.B1
^THERE ARE THREE NEW SWITCHES SUPPORTED IN ^^LOGIN\\ VERSION 60.
.B1.LM 15.TS15.I-15
^^/UFDPROT:\\NNN ^SET PROTECTION OF CREATED ^U^F^D'S TO NNN
.I-15
^^/SFDPROT:\\NNN ^SET PROTECTION OF CREATED ^S^F^D'S TO NNN
.I-15
^^/DEFPROT:\\NNN ^SET DEFAULT PROTECTION FOR ALL FILES CREATED
DURING THIS TERMINAL SESSION TO NNN (REQUIRES MONITOR 6.03 OR LATER)
.B1.LM 0.TS5
^THERE ARE ALSO TWO SWITCHES CONTROLLED BY ASSEMBLY CONDITIONAL
SWITCHES WHICH ARE NORMALLY OFF. ^THIS CODE IS UNSUPPORTED AND IS
SUPPLIED SOLELY AS A CONVENIENCE TO THE USER SITE.
.B1
^ASSEMBLY SWITCH ^^PSWCHG\\ TURNS ON CODE TO ALLOW USERS
TO CHANGE THEIR OWN PASSWORDS. ^IF THIS SWITCH IS TURNED ON, IT
ENABLES THE /^^PASSWORD\\ SWITCH. ^THIS SWITCH IS IGNORED IN
^^SWITCH.INI\\, BUT IF TYPED ON THE ^^LOGIN\\ COMMAND LINE IT CAUSES
^^LOGIN\\ TO PROMPT "^NEW PASSWORD:#" AFTER THE OLD ONE HAS BEEN
VALIDATED. ^THE USERS TYPES HIS NEW PASSWORD (WHICH IS ECHOED TO
PREVENT TYPING ERRORS FROM LOCKING A USER OUT OF HIS OWN ^^PPN\\).
^THIS PASSWORD IS THEN WRITTEN INTO ^^ACCT.SYS\\ AND BECOMES THE
USER'S NEW PASSWORD.
.B1
^ASSEMBLY SWITCH ^^NCRYPT\\ TURNS ON CODE THAT PERFORMS
A NON-INVERTIBLE HASHING FUNCTION ON THE USER'S PASSWORD BEFORE
CHECKING IT AGAINST THE ONE IN ^^ACCT.SYS\\. ^THIS ASSUMES THAT
THE PASSWORD WAS HASHED BY THE SAME FUNCTION BEFORE BEING STORED
IN ^^ACCT.SYS\\. ^THE PURPOSE OF DOING THIS IS THAT IF ONLY HASHED
PASSWORDS ARE STORED, THEN EVEN THOUGH SOMEONE GAINS ACCESS
TO ^^ACCT.SYS\\, HE STILL CANNOT USE THE PASSWORDS SINCE THERE IS
NO WAY TO CONVERT THE HASHED PASSWORDS BACK INTO THE REAL ONES. ^THE
ONE DRAWBACK IS THAT IF A USER FORGETS HIS PASSWORD, THERE IS NO WAY
TO FIND IT OUT: HE MUST SIMPLY CREATE A NEW ONE. ^^REACT\\ IS NOT
YET CODED TO HASH PASSWORDS BEFORE STORING THEM IN ^^ACCT.SYS\\,
BUT IT IS A SIMPLE MATTER TO COPY THE ROUTINE FROM ^^LOGIN\\
(IT IS ONLY HALF A PAGE LONG) INTO ^^REACT\\.
.B3
3.0 <KNOWN <BUGS <AND <DEFICIENCIES
.B1
^NONE.
.B3
4.0 <INSTALLATION <INSTRUCTIONS
.B1
^PREVIOUS VERSIONS OF ^^LOGIN\\ NEVER CHECKED
THE "MAY LOG IN UNDER ^BATCH" BIT IN ^^ACCT.SYS\\ FOR [1,2] JOBS. ^SINCE
^^LOGIN\\ VERSION 60 NOW CHECKS THIS BIT, YOU SHOULD BE SURE
THAT THIS BIT IS SET IF YOU PLAN TO RUN BATCH JOBS UNDER [1,2].
^PREVIOUS VERSIONS OF ^^LOGIN\\ ALSO NEVER CHECKED
THE BIT WHICH SAYS "MAY LOG IN AS A ^BATCH JOB SUBJOB".
^SINCE THIS BIT IS NOW CHECKED, YOU MAY WISH TO REVISE YOUR
^^ACCT.SYS\\ ENTRIES IF YOU PLAN TO HAVE ^BATCH JOBS LOG IN
SUBJOBS IN ANY MANNER.

.B3
1.0 <SUMMARY
.B1
^THE PRINCIPLE PURPOSE OF THIS RELEASE IS TO PROVIDE SUPPORT
FOR THE NEW FEATURES OF THE 6.02 ^MONITOR; SPECIFICALLY, TO SET
^^ENQ/DEQ\\ QUOTAS AND TO PLACE THE JOB IN THE APPROPRIATE SCHEDULER
CLASS ON ^LOGIN. ^ALSO INCLUDED ARE SEVERAL BUG FIXES AND
HOOKS FOR EXTERNAL ACCOUNTING MODULES TO SIMPLIFY THE TASK OF ADDING
EXTRA ACCOUNTING LOGIC TO ^^LOGIN\\.
.B1
^^LOGIN\\ IS DOCUMENTED IN ^SOFTWARE ^NOTEBOOOK ^VOL. 2^A.
.B1
^THIS VERSION OF ^^LOGIN\\ SUPERSEDES ALL PREVIOUS VERSIONS.
^IT RUNS UNDER ALL SUPPORTED MONITORS. ^THE ^^DATE75\\ PROJECT IS
FULLY IMPLEMENTED. ^^LOGIN\\ ^V57 HAS BEEN TESTED SUCCESSFULLY UNDER
5.07^A, 5.07^B/6.01^B, AND 6.02.
.B1
^THE FOLLOWING ^^CUSP\\S OR LATER MUST BE USED WITH ^^LOGIN\\ ^V57:

4.1 ^^ENQ/DEQ\\:
.B1
^^REACT\\ ^V31 HAS AN EXTRA QUESTION WHICH ASKS FOR THE
USER'S ^^ENQ/DEQ\\ QUOTA. ^THIS IS STORED IN BITS 27-35 OF
THE EXPIRATION DATE WORD, THE RIGHT HALF OF WHICH WAS PREVIOUSLY
UNUSED. ^^LOGIN\\ READS THIS QUANTITY AND PASSES IT TO THE ^MONITOR
AS THE USER'S ^^ENQ/DEQ\\ QUOTA. ^HOWEVER, IF THESE BITS ARE ALL ONES,
^^LOGIN\\ DOES NOT SET THE QUOTA. ^WHEN THE USER FIRST DOES AN ^^ENQ\\, ^MONITOR WILL THEN SUPPLY THE CURRENT SYSTEM-WIDE DEFAULT QUOTA.
.PG.B2
4.2 ^SCHEDULER ^PARAMETERS:
.B1
^^REACT\\ ^V31 HAS ANOTHER NEW QUESTION WHICH ASKS FOR THE USER'S
SCHEDULER TYPE. ^THIS 9-BIT QUANTITY IS STORED IN BITS 18-26 OF THE
EXPIRATION DATE, THE RIGHT HALF OF WHICH WAS PREVIOUSLY UNUSED.
.B1
^WHEN ^^LOGIN\\ ^V57 IS FIRST RUN, IT READS A NEW ACCOUNTING
FILE CALLED ^^SCDMAP.SYS\\ INTO ITS HIGH SEGMENT. ^THIS FILE
PROVIDES A MAPPING BETWEEN SCHEDULER TYPES, WHICH ARE STORED IN
^^ACCT.SYS\\, AND SCHEDULER CLASSES, WHICH IS WHAT THE SCHEDULER AND
^^SCHED.UUO\\ TALK ABOUT. ^WHEN THE USER LOGS IN, ^^LOGIN\\ GETS
HIS SCHEDULER TYPE FROM ^^ACCT.SYS\\. ^^SCDMAP.SYS\\ IS A BINARY
FILE WITH 4 ENTRIES PER WORD. ^ENTRY NUMBER N IS THE SCHEDULER
CLASS FOR TYPE N. ^IN OTHER WORDS, ^^SCDMAP.SYS\\ IS SET UP
SOMEWHAT LIKE A PAGE MAP. ^^LOGIN\\ COMPUTES AN INDEX INTO ^^SCDMAP.SYS\\
FROM THE SCHEDULER TYPE READ FROM ^^ACCT.SYS\\ AND PICKS UP THE
APPROPRIATE SCHEDULER CLASS FROM ITS COPY OF ^^SCDMAP.SYS\\ IN ITS
HIGH SEGMENT.
.B1
^^SCDMAP.SYS\\ HAS TWO PARALLEL TABLES IN IT. ^THE FIRST
512 ENTRIES, OR 128 WORDS, CONTAIN THE MAPPINGS FROM TYPES TO CLASSES
FOR TIMESHARING JOBS. ^THE SECOND 512 ENTRIES CONTAIN THE MAPPING
OF TYPES TO CLASSES FOR BATCH JOBS. ^THUS, SYSTEM ADMINISTRATORS
CAN SPECIFY DIFFERENT SCHEDULING PRIORITIES FOR BATCH JOBS AND
TIMESHARING JOBS.
.B1
^^SCDMAP.SYS\\ IS GENERATED BY A NEW ^^CUSP\\ CALLED ^^SCDSET\\.
^THIS ^^CUSP\\ ALSO TWEAKS THE SCHEDULER ON THE FLY. ^THIS ^^CUSP\\
MUST BE RUN BEFORE BRINGING UP ^^LOGIN\\ ^V57 IN ORDER TO CREATE
^^SCDMAP.SYS\\. ^IF ^^SCDMAP.SYS\\ DOES NOT EXIST OR CANNOT
BE READ, THE FIRST USER TO RUN ^^LOGIN\\ WILL RECEIVE THE WARNING
MESSAGE:
.B1.I5
^CANNOT FIND ^^SCDMAP.SYS\\. ^PLEASE CALL THE OPERATOR.
.B1
^ONLY THE FIRST USER WILL RECEIVE THIS MESSAGE AS ^^LOGIN\\ SETS
A FLAG IN ITS HI SEG AND IF IT COULD NOT READ ^^SCDMAP.SYS\\
THE FIRST TIME, IT DOESN'T ATTEMPT TO DO ANY OF THE SCHEDULER
STUFF. ^INSTALLATIONS WHICH ARE RUNNING ^MONITORS WITHOUT
THE NEW SCHEDULER NEED NOT CREATE ^^SCDMAP.SYS\\ AS ^^LOGIN\\ CHECKS
THE SECOND STATES WORD IN ^MONITOR AND DOES NOT ATTEMPT ANY OF
THE SCHEDULER SETTING CODE IF THE ^MONITOR DOES NOT SUPPORT IT.
^IT SHOULD BE MENTIONED THAT IF ANY OF THE ACCOUNTING
FILES (NOT ONLY ^^SCDMAP.SYS\\) ARE MODIFIED WHILE THE SYSTEM IS
RUNNING, ^^LOGIN\\ SHOULD BE RENAMED TO ITSELF. ^THIS WILL SUPERSEDE
THE COPY OF ^^LOGIN\\ ON THE SWAPPING SPACE WHICH WOULD
OTHERWISE CONTAIN OBSOLETE INDICES INTO ^^ACCT.SYS\\ AND ^^AUXACC.SYS\\
AND AN OBSOLETE COPY OF ^^SCDMAP.SYS\\. ^FOR MORE DETAILED INFORMATION CONCERNING THE NEW SCHEDULER AND ITS PARAMETERS,
SEE THE ^^DOC\\ FILE FOR ^^SCDSET\\.

1.1##^FUNCTION OF <LOGIN
.B1
^^LOGIN\\ IS USED TO VERIFY A USERS RIGHT TO ACCESS THE
SYSTEM. ^^LOGIN\\ DOES PASSWORD AND NAME CHECKING AS REQUIRED.
^^LOGIN\\ LOGS THE USER INTO THE SYSTEM BY CREATING DIRECTORIES,
WRITING AN ACCOUNTING RECORD, AND SETTING USER PARAMETERS AS DIRECTED BY
THE ACCOUNTING FILES AND SWITCHES ON THE ^^LOGIN\\
LINE AND IN ^^SWITCH.INI\\. ^^LOGIN\\ ALSO VERIFIES THAT AN ^ATTACH\\
COMMAND IS VALID.

^THE NET EFFECT IS TO ALLOW USER TO SPECIFY
HIS NAME ON THE JOB CARD AND GET IT STORED
CORRECTLY IN THE JOB TABLES. ^IF THE USER
DOES NOT NEED HIS NAME CHECKED HE CAN SPECIFY
ANY NAME HE WANTS. ^TO DEFEAT THIS FOR INSTALLATIONS
WHICH WANT TO FORCE THE NAME IN ^^ACCT.SYS\\
