Here is the module that I used to allow saslauthd to work with kerberos5, allow
access to the kaytab and access to tmp_t so it can create cache files. Is there
a better way to handle this other than giving it all this access rights to tmp_t?

module mysaslauthd 1.0.8;

require {
        class dir { search write add_name remove_name };
        class file { getattr lock read write create rename unlink };
        type krb5_keytab_t;
        type saslauthd_t;
        type tmp_t;
        role system_r;
};

allow saslauthd_t krb5_keytab_t:file read;
allow saslauthd_t krb5_keytab_t:file lock;
allow saslauthd_t tmp_t:dir search;
allow saslauthd_t tmp_t:file { getattr read write create rename unlink };
allow saslauthd_t tmp_t:dir { search write add_name remove_name };
