I have an NFS share with user home directories mounted on a web server. I want to enable UserDir in apache, but the home directories are not a straight-forward "/home/username" path. Instead, they're organized into a hierarchy based on their username. For example, a username may be ab1234 (always two letters followed by four numbers). The hierarchy for that home folder would be /ab/ab12/ab1234.
In the sssd.conf I know that there are basic parameters for parsing the username out of the username@domain string, but is there anything that can parse that username further into parts?
