[LightDM] Building on XStreamOS/illumos

[Gabriele Bulfon]

Thanks Guido,
our XStreamOS features recent xorg 1.14.5 as from oracle open repo.
I assume those issues you talk about are already present in this.
Do you think so?
I will definetly look at the gdm patch sets to see if and how they can fit into lightdm.
Anyway, XStreamOS Desktop does not include gdm at the moment (we would like to have lightdm instead).
So I don't have pam files for gdm.
Can you point me to some files to see around?
Gabriele.

Can you send me your log with PAM messages?
PAM policy is configured in /etc/pam.conf, I suppose you haven't
set that up correctly. /etc/pam.d/ where LightDM installs its
policy files is only supported on Solaris11.1 and thus does
not work on Illumos. Furthermore you need to adapt the policy
anyways, the existing GDM policy should be a good starting point
to do that.
There are other issues relating to proper Solaris integration as
well, you need to patch in sdtlogin support so that the X server
can safely drop root privileges on login, support logindevperm
for correct device permissions and possibly RBAC in order to
enable shutdown/reboot.
For some pointers have a look at
http://www.x.org/wiki/Events/XDC2012/XDC2012AbstractAlanCoopersmith/SolarisXorgPrivileges.pdf
and the gdm patch sets at
https://hg.openindiana.org/sustaining/oi_151a/spec-files/file/db10202d5f6d
https://hg.java.net/hg/solaris-desktop~spec-files/file/a2add17d60e2
BTW, is it absolutely necessary to have a lightdm user? I run it as root.
The LightDM daemon runs with root privileges, however the greeter
needs to run as an unprivileged user. Running a user-facing GUI
for authentication with root privileges is just a security
disaster waiting to happen.
