I've read some FAQs trying to resolve the following error: GSSAPI Error: Miscellaneous failure (see text) (unable to find realm of host stub) They all suggest editing the krb5.conf file to add the default_realm attribute. Due to some issues with SELinux policy, I'd like to avoid editing system files in my application code... I've tried using `krb5_set_default_realm` but this doesn't seem to affect `ldap_sasl_bind`. Is there an alternative to specifying the default realm in krb5.conf? Thanks.
