======Other Days======
======December 2nd, 2015======
=====OpenBSD LDAP authentication via XDM=====
So this has been slightly enigmatic... trying to get logins working via xdm (it seemed to not be querying LDAP).
I re-checked my config, using the best reference:
* https://www.talamasca.pl/projects/talamasca/wiki/OpenBSD_with_LDAP_-_system_authentication
I tried checking the logs.
But, the issue was apparently NOT LDAP.
This helpful post clued me in:
* http://webcache.googleusercontent.com/search?q=cache:bzDSclBupEYJ:www.monkey.org/openbsd/archive/ports/0405/msg00421.html+&cd=7&hl=en&ct=clnk&gl=us
For if we start **xdm** with full debugging verbosity:
# xdm -debug 255 -nodaemon
...
We can clearly see it is kicking us out because the user's default shell (bash) is NOT listed in /etc/shells. Adding it fixed the problem and everything lit up as it should.
=====xdm config=====
Now that I've gotten the xdm login situation resolved, it is time to apply configuration tweaks.
======December 1st, 2015======
=====The future: vertical OpenBSD desktops=====
I thought to tinker with rotating the display orientations to the left, so monitors could be turned on their sides (freeing up a significant amount of desk space).
The basic trick is with **xrandr**, which I accomplished in **/etc/X11/xinit/xinitrc**:
xrandr --output VGA-0 --off --output DisplayPort-0 --mode 1280x1024 --pos 1280x0 --rotate left --output DVI-0 --mode 1280x1024 --pos 0x0 --rotate left
The lingering problem is that XDM logins do not appear to be workingeee
