libserdes with user/apssword

Hi, I'm working with C

1) with which version of avro is serdes compatible ?
2) Is it possible, with serdes to pass the user and password to access the Schema Registry?

I've done some research, but I haven't found anything.

Thanks in advance

No file, test, or entry point is named. Start by checking the libserdes documentation and its Schema Registry and Avro integration APIs for supported Avro versions and user/password configuration. Done means documenting verified answers to both questions, including any limitations.
