Dear maintainers,
I noticed that when krb5_get_init_creds_password is called using an incorrect password, the error code returned is KRB5KDC_ERR_PREAUTH_FAILED (using release 1.17). This is not among the possible return values mentioned in https://web.mit.edu/kerberos/krb5-latest/doc/appdev/refs/api/krb5_get_init_creds_password.html.
Due to the necessary external setup, it is a bit hard to provide a minimal working example, but the libkrb5 source itself seems to agree that this is a possible return value (see e.g. https://github.com/krb5/krb5/blob/krb5-1.17-final/src/clients/kinit/kinit.c#L773-L811).
Possibly the list of return values in the documentation is not meant to be exhaustive; in that case the documentation should say so.
Kind regards,
Fabian Müller
