Sync users from chalmers ldap (ldap.chalmers.se) to Gamma, adding them to the whitelist so that enrolled students can create accounts in Gamma.
The script requires three environment variables - GAMMA_API_KEY_ID, GAMMA_API_KEY_SECRET, and LDAP_COMMON_NAME.
Normally the group should be s_passer_prog_tkite, but new students are not added to this group before the semester starts, but are temporarily added to a group named something along the lines of s_studier_forvantade_programdeltagare_chalmers_tkite_h21, but will vary year to year.
An API key can be created in Gamma if you're an admin.
Example:
$ GAMMA_API_KEY_ID=xxxxx GAMMA_API_KEY_SECRET=xxxxx LDAP_COMMON_NAME=s_passer_prog_tkite cargo run --release
