What package versions you've tested that with?
Comment 2 Levente Farkas 2004-12-27 15:58:01 EST
on the latest fully updated rhel3
Comment 3 Tomas Mraz 2004-12-28 03:31:40 EST
So why do you report it on FC devel?

There is nothing pam_mkhomedir can do with the problem. You must
disable privilege separation.

However the newest openssh (FC3, RHEL4) doesn't exhibit this problem.
Comment 4 Levente Farkas 2004-12-28 05:20:48 EST
sorry about that:-( i'd like to report it on rhel. anyway i don't
think so the solution is to disable privilege separation! rather then
fix it at the ssh level even in the next rhel 3 updates.

Try packages from http://people.redhat.com/tmraz/testing/ which should
fix the problem. 
Of course they are unofficial so the standard disclaimers apply. They
aren't guaranteed to work and they can eat your data or even computer.

Should be fixed with the latest errata.
