That's the official(**default**) table name.
```ERROR: auth_db [auth_db_mod.c:308]: auth_fixup(): error during table version check.```
Error seems pretty clear to me, the version value is wrong. It has the module name, so you can check [AUTH_DB Module db structure](https://www.kamailio.org/docs/db-tables/kamailio-db-5.2.x.html#idm1021174668) and find out what is missing.
