Is there a way to set up the maps to mount a users home directory if they are divided up under a directory that is the first letter of their username without mounting all such directories for every user? We have thousands of students needing home directories and so they have divided up this way. Example: /home/students/a/aardvark or /home/students/b/bugsbunny. The docs I have read on autofs maps haven't been very clear on how to define this kind of mapping, especially in FreeIPA.
Kristian,
The doc that helped me a lot is [1]. I think you just need to create 26 entries in `auto_home` using a wildcard at the end of each key (ie `a*`, `b*`, etc). Then, for each user, set their home directory to the correct full path.

OK. So I created the keys for each letter in this format: a* -fstype=nfs4,soft,intr,rsize=8192,wsize=8192,tcp fileserver.chem.byu.edu: /export/home/students/a/:&
It still doesn't seem to be mounting the directories as it should and I am not understanding why. The syntax of the key entries appears correct as far as I can tell. Am I missing something?

I don't think that first entry is a glob. I believe that * just means any. & is shorthand for the matching key so
* -fstype=nfs4,soft,intr,rsize=8192,wsize=8192,tcp fileserver.chem.byu.edu:/export/home/students/&
Just substitutes whatever the matching key (*) to &.
I assume this is in some auto.home-like map.
I don't claim to know a lot about autofs but you might try creating an auto.home-a, auto.home-b, etc.
auto.master contains:
/export/home/students/a auto.home-a /export/home/students/b auto.home-b
This of course assumes that the homedir in the user entry is /export/home/students/<letter>/<login>
This feels like it should be a solved problem but my git-fu wasn't able to find anything definitive. You might try the autofs community.

I also have no idea if that will work, but running "automount -vvvf" in a terminal very likely produces enough traces to see how the map is handled. I think that could help investigating what might work.
