Under Solaris 2.x, login failure information is not all logged
in one place. The tty and remote source host, if any, are written
to /var/adm/messages, while the account name that was attempted,
along with the tty but *not* the source host, is logged in
/var/adm/loginlog *if it exists*. /var/adm/loginlog is not created
by default when the OS is installed; it has to be touched and
should be mode 600.
Solaris 2.6 does not write anything in /var/adm/loginlog even if
it does exist. This has been assigned bug ID 4096961.
I also spoke to Sun about the fact that from the standpoint of
monitoring security at a large site, complete information needs to
be in one file; it is difficult to automate cross-referencing of
multiple files, especially when /var/adm/messages summarizes
repeated failures while /var/adm/loginlog does not. This has been
assigned bug ID 4101839.
