As I recall, telnetd and in.telnetd (your example) uses
/bin/login to manage user logins. There is a configuration file for /bin/login called
login.defs :
Quote:
NAME
/etc/login.defs - Login configuration
DESCRIPTION
The /etc/login.defs file defines the site-specific config-
uration for the shadow login suite. This file is
required. Absence of this file will not prevent system
operation, but will probably result in undesirable opera-
tion.
This file is a readable text file, each line of the file
describing one configuration parameter. The lines consist
of a configuration name and value, seperated by whites-
pace. Blank lines and comment lines are ignored. Com-
ments are introduced with a `#' pound sign and the pound
sign must be the first non-white character of the line.
Parameter values may be of four types: strings, booleans,
numbers, and long numbers. A string is comprised of any
printable characters. A boolean should be either the
and in the man page, the configuration for the logging behavior of
/bin/login is configured (just a few examples):
Quote:
FAILLOG_ENAB (boolean)
If yes then login failures will be accumulated in
/var/log/faillog in a faillog(8) format.
FAIL_DELAY (number)
Delay time in seconds after each failed login
attempt.
Does this help, or were you looking for more generic syslog.conf information not related to login and telnetd?

CHSH(1) User Commands CHSH(1)
NAME
chsh - change login shell
SYNOPSIS
chsh [options] [LOGIN]
DESCRIPTION
The chsh command changes the user login shell. This determines the name of the user's initial login command. A normal user may only change
the login shell for her own account; the superuser may change the login shell for any account.
OPTIONS
The options which apply to the chsh command are:
-h, --help
Display help message and exit.
-R, --root CHROOT_DIR
Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory.
-s, --shell SHELL
The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.
If the -s option is not selected, chsh operates in an interactive fashion, prompting the user with the current login shell. Enter the new
value to change the shell, or leave the line blank to use the current one. The current shell is displayed between a pair of [ ] marks.
NOTE
The only restriction placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the superuser,
and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh
in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell
back to its original value.
FILES
/etc/passwd
User account information.
/etc/shells
List of valid login shells.
/etc/login.defs
Shadow password suite configuration.

chfn(1), login.defs(5), passwd(5).
