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.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.
