terminal user id

[ekan]

I have strange problem.I would appreciate your valuable expertise .
Sometimes when a user logs in to their UNIX account, their logname is incorrectly set to the previous user of that terminal id.Reports generated by the new user are saved into the old user's home directory but are owned by the new user, thus the new user can't find them and neither person can delete them.

L.S.

It seems that HOME is not set correctly.
It's the responsibility of login to set HOME, LOGNAME, MAIL, PATH and SHELL.
Can you check these vatiables?

Can one modify the HOME variable in the shell?
In .profile etcetera?

By the way, do the users have write permission on someone else's homedir?
