# Differences between Heimdal and MIT Kerberos API

`krb5_auth_con_getaddrs()` | H5l: If either of the pointers to local_addr and remote_addr is not NULL, it is freed first and then reallocated before being populated with the content of corresponding address from authentication context.
`krb5_auth_con_setaddrs()` | H5l: If either address is NULL, the previous address remains in place
`krb5_auth_con_setports()` | H5l: Not implemented as of version 1.3.3
`krb5_auth_con_setrecvsubkey()` | H5l: If either port is NULL, the previous port remains in place
`krb5_auth_con_setsendsubkey()` | H5l: Not implemented as of version 1.3.3
`krb5_cc_set_config()` | MIT: Before version 1.10 it was assumed that the last argument data is ALWAYS non-zero.
`krb5_cccol_last_change_time()` | H5l takes 3 arguments: krb5_context context, const char *type, krb5_timestamp *change_time MIT takes two arguments: krb5_context context, krb5_timestamp *change_time
`krb5_set_default_realm()` | H5l: Caches the computed default realm context field. If the second argument is NULL, it tries to retrieve it from libdefaults or DNS. MIT: Computes the default realm each time if it wasn’t explicitly set in the context
