Thank you for responding. Both libutempter-devel and pam-devel were

Hi,
To get a clean environment I removed cde, including /var/dt and
reinstalled.
Should dtsession be linked against both libraries?
No - utempter is used for writing utmp/utmpx files, and only the
terminal wants to do that.
dtsession and dtlogin are the only ones that need PAM support (to verify
your login/password).
So the list you posted is correct.
# find /usr/dt/bin -type f -print -exec sh -c "ldd {} | grep -e libpam
-e libutemp " \;
/usr/dt/bin/ttrm
[...]
--- starting /usr/dt/bin/dtappgather &

not execing /home/murrayb/.profile (see /home/murrayb/.dtprofile)
changeOwnerGroup: /var/dt/appconfig| : Operation not permitted
changeOwnerGroup: /var/dt/appconfig/appmanager| : Operation not permitted
This might explain your dtfile app list issue. I reality, dtappgather
should just create these links in the ~/.dt/ dir somewhere, but this is
not supported currently.
I also found this in my system log;

Probably bad error handling of the above errors.
Setuid on /usr/dt/bin/dtsession made no difference.
Yeah - it's trying to use the PAM library to validate your username/pw,
but seems to be failing somewhere along the line. Is there anything of
interest in /var/log/secure* ?

Disabling selinux also made no difference.
Kind regards

I've built and installed CDE 2.4.0 using the spec files, etc from;

I did make some minor changes to the spec file but it's
largely unchanged.
I'm able to run a CDE session from gdm but I have the following
issues.
1. The lock screen can't be unlocked. It just remains after
entering the user password to unlock.
This one may be caused by missing dev packages. In 2.4.0, support
for PAM an utempter was added - this makes it possible to run
dtterm and dtsession w/o needing SUID root. Make sure that the
libutempter-devel and pam-devel packages are installed.
1. The Application Manager has a "generic-display-0" folder in
the root, rather than the actual applications. If I open
that folder, the applications are shown.
That one, I've not yet seen.
I've attached some pics for reference.
Here's some info which may/may not help.

Seems like an issue determining your hostname.

I have tried running with both of these files setuid but it
doesn't make any difference.
Try making sure those packages I mentioned above are present.
dtsession is what handles the password unlock on behalf of dtscreen.
Also, FYI, I still have selinux active. I haven't tried running
with selinux disabled.
I have never run with that enabled on centos 8 (well, now I am
running Rocky linux in a VM), so I don't know what effect that
would have.
What have I broken in my build/install?
I think as far as the unlocking at least, you just need the
utempter package. Places you can look are ~/.dt/errorlog,
~/.dt/startlog, and perhaps other files in ~/.dt/
