Problem with cleaning utmp entry

[Bosko Radivojevic]

Hello

I have problem with OpenSSH 2.1.1p1 on libc5 system (Slackware 4). I'm not
sure if I had those problems with 1.2.x version of OpenSSH (on the same
system), but I don't think so.

When someone ends ssh session (logout, or something) utmp entry for that
user doesn't get erased from UTMP file. In 'finger' I can see a lot of
multiplicied users that are not actually logged in.

WTMP logging is also broken. (there is no entries at all)

I don't have those problems on glibc2 systems (slack7), and I would be
very happy if problem with libc5 and logging could be solved.

Greetings

PS. Part of ./configure that may be useful:
checking for ut_host field in utmp.h... yes
checking for ut_host field in utmpx.h... no
checking for syslen field in utmpx.h... no
checking for ut_pid field in utmp.h... yes
checking for ut_type field in utmp.h... yes
checking for ut_type field in utmpx.h... no
checking for ut_tv field in utmp.h... no
checking for ut_id field in utmp.h... yes
checking for ut_addr field in utmp.h... yes
checking for ut_addr field in utmpx.h... no
checking for ut_addr_v6 field in utmp.h... no
checking for ut_addr_v6 field in utmpx.h... no
checking for ut_exit field in utmp.h... no
checking for ut_time field in utmp.h... yes
checking for ut_time field in utmpx.h... no
checking for ut_tv field in utmpx.h... no

PPS. Part of config.h (after doing configure):
