django.db.utils.OperationalError: (1071, 'Specified key was too long; max key length is 3072 bytes') about django-cas-ng

[cuuush]

as a temporary workaround, you can downgrade to mysql 5.7. this issue seems to apply to mysql 8

[cuuush]

the reason is due to mysql8 default character set being utf8mb4, which uses 4 bytes per character. The max length of the charfields is 1024 X 4 bytes which is greater than 3072. is there a reason why these fields need to be so large? CAS specification recommends supporting up to 256 characters.

https://github.com/gregbaker/django-cas-ng is a fork that fixes this, no idea why this hasn't been merged into a release since it is a known issue; i referenced the (very quickly marked as stale) original issue above
