We are running QNX 4.24 on several systems. These systems NFS mount users home directories from a Unix filesystem. Several users have a Unix UID > 32-bits. This poses a problem when users attempt to RWX their home directories from QNX. We have a kludge to this problem by setting the UID in the QNX password file to the truncated 32-bit equivalent of the Unix UID (i.e. Unix Id = 34373, QNX Id = -31163).
My questions is this, what imposes the 32-bit UID limit in QNX? Is it the filesystem, the process manager, or what? Neutrino does not have a problem with UIDs > 32-bit. Is it possible to run a QNXRTP equivalent processes which will overcome this problem (i.e. rlogind, su)
Thank You,
Pete

QNX4 filesystem imposes 16bit UIG/GID actually. If you only deal with NFS,
that should not affect you much. I have no idea if other components of QNX4
impose any limitations on that.

hi, we had a similar problem with OSF and QNX 4: we tried to solve this by
avoiding to give OSF users a uid and gid greater than 32000 (2^16-1). so we
could maintain a 16-bite compatibility between the two systems
