How to block temporary account in mysql user table

I have a problem about vault account .
Each call to the vault will generate three temporary account in MYSQL user table.With the operation,the account will become more and more.
I wonder if there are some ways to block the temporary account or delete those account by modifying the configuration file.

Hi @meadowhuhu!

Could you elaborate a bit more on what you mean with “vault account”?
Do you mean Vault’s MySQL secrets engine? Or do you mean Vault’s MySQL storage engine?

Also, it would be super helpful to get more information on what you have done (configuration etc.) and what do you exactly mean with “call to vault”.
