[Jailkit-users] Problem with jk_chrootsh

[Dave Augustus]

I have reviewed the email archives about this problem but I am unable to
login via ssh into a chroot jail. Su to the user works fine, however.

Any clues greatly appreciated!

This is a 64 bit Centos 4 (RHEL4) with SELinux disabled..

Here is the contents of my /var/log/secure logfile:

Aug 10 08:19:27 mars sshd(pam_unix)[15115]: session opened for user
myusername by (uid=0)
Aug 10 08:19:27 mars jk_chrootsh[15116]: abort, failed to get user
information for user ID 516: Bad file descriptor, check /etc/passwd
Aug 10 08:19:27 mars sshd(pam_unix)[15115]: session closed for user
myusername

Here are the tracefiles:
