No user exists for uid 721001106 when running ssh command within SSH chroot directory
0
I am running debian 8 with SSSD authentication. The authentication works and ssh works fine. I have copied all libraries etc over to my SSH chrootdirectory and all my applications work except ssh which has the error:
No user exists for uid 721001106
I have ran ltrace to ensure I got all the libraries and files. Next I tried symbolic links to the files where I could.
Ltrace where trace=open

Within Chroot:
uid=721001106 gid=721000513 groups=721000513,721001108
My questions are, why is this happening and where is it trying to read from and failing.
Oh, also, I did a mount --bind /proc /path/to/jail/proc
Still no difference...
Any ideas what to try next?
Many Thanks,
Luke
