Number of login times
Hi! I'm currently using AIX 4.3 and would like to know where can i find to see that there's a restriction on the number of login times a user can have. Example, I want to see whether user A has only 1 login while user B can have 2 logins (without logging off the first one).
Would I be able to see it in the lsuser file?
i know that in my company, certain users can login several times without encountering "Too many logons" while certain users can only log in once.
Hope someone can help me out. thanks

LOGIN(1) BSD General Commands Manual LOGIN(1)
NAME
login -- log into the computer
SYNOPSIS
login [-pq] [-h hostname] [user]
login -f [-lpq] [-h hostname] [user [prog [args...]]]
DESCRIPTION
The login utility logs users (and pseudo-users) into the computer system.
If no user is specified, or if a user is specified and authentication of the user fails, login prompts for a user name. Authentication of
users is configurable via pam(8). Password authentication is the default.
The following options are available:
-f When a user name is specified, this option indicates that proper authentication has already been done and that no password need be
requested. This option may only be used by the super-user or when an already logged in user is logging in as themselves.
With the -f option, an alternate program (and any arguments) may be run instead of the user's default shell. The program and argu-
ments follows the user name.
-h Specify the host from which the connection was received. It is used by various daemons such as telnetd(8). This option may only be
used by the super-user.
-l Tells the program executed by login that this is not a login session (by convention, a login session is signalled to the program with
a hyphen as the first character of argv[0]; this option disables that), and prevents it from chdir(2)ing to the user's home direc-
tory. The default is to add the hyphen (this is a login session).
-p By default, login discards any previous environment. The -p option disables this behavior.
-q This forces quiet logins, as if a .hushlogin is present.
If the file /etc/nologin exists, login dislays its contents to the user and exits. This is used by shutdown(8) to prevent users from logging
in when the system is about to go down.
Immediately after logging a user in, login displays the system copyright notice, the date and time the user last logged in, the message of
the day as well as other information. If the file .hushlogin exists in the user's home directory, all of these messages are suppressed. -q
is specified, all of these messages are suppressed. This is to simplify logins for non-human users, such as uucp(1). login then records an
entry in utmpx(5) and the like, and executes the user's command interpreter (or the program specified on the command line if -f is speci-
fied).
The login utility enters information into the environment (see environ(7)) specifying the user's home directory (HOME), command interpreter
(SHELL), search path (PATH), terminal type (TERM) and user name (both LOGNAME and USER).
Some shells may provide a builtin login command which is similar or identical to this utility. Consult the builtin(1) manual page.
The login utility will submit an audit record when login succeeds or fails. Failure to determine the current auditing state will result in
an error exit from login.
