krb524_convert_creds_kdc, krb524_convert_creds_kdc_ccache -- converts Kerberos 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 cre-
dential that is stored in credentials.
krb524_convert_creds_kdc_ccache() is different 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 Kerberos 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.
