krb524_convert_creds_kdc, krb524_convert_creds_kdc_ccache — converts Ker‐
beros 5 credentials to Kerberos 4 credentials
Kerberos 5 Library (libkrb5, -lkrb5)
krb524_convert_creds_kdc(krb5_context context, krb5_creds *in_cred,
struct credentials *v4creds);
krb524_convert_creds_kdc_ccache(krb5_context context, krb5_ccache ccache,
krb5_creds *in_cred, struct credentials *v4creds);
Convert the Kerberos 5 credential to Kerberos 4 credential. This is done
by sending them to the 524 service in the KDC.
krb524_convert_creds_kdc() converts the Kerberos 5 credential in in_cred
to Kerberos 4 credential that is stored in credentials.
krb524_convert_creds_kdc_ccache() is diffrent from
krb524_convert_creds_kdc() in that way that if in_cred doesn't contain a
DES session key, then a new one is fetched from the KDC and stored in the
cred cache ccache, and then the KDC is queried to convert the credential.
This interfaces are used to make the migration to Kerberos 5 from Ker‐
beros 4 easier. There are few services that still need Kerberos 4, and
this is mainly for compatibility for those services. Some services, like
AFS, really have Kerberos 5 supports, but still uses the 524 interface to
make the migration easier.
