# NAME

`krb524_convert_creds_kdc`, `krb524_convert_creds_kdc_ccache` — converts Kerberos 5 credentials to Kerberos 4 credentials

# LIBRARY

Kerberos 5 Library (libkrb5, -lkrb5)

# SYNOPSIS

`#include <krb5/krb5.h>`

krb5_error_code
`krb524_convert_creds_kdc`(krb5_context context, krb5_creds *in_cred, struct credentials *v4creds);

krb5_error_code
`krb524_convert_creds_kdc_ccache`(krb5_context context, krb5_ccache ccache, krb5_creds *in_cred, struct credentials *v4creds);

# DESCRIPTION

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 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.
