Looking at the preprocessed output (gcc -E), these are the relevant parts of
the included header files.
/usr/include/krb5_asn1.h:18:typedef char *heim_general_string;
/usr/include/krb5_asn1.h:266:typedef heim_general_string Realm;
/usr/include/krb5.h:289:typedef Realm krb5_realm;
/usr/include/krb5-protos.h:2384:krb5_realm*
/usr/include/krb5-protos.h:2385:krb5_princ_realm (
/usr/include/krb5-protos.h:2386:        krb5_context /*context*/,
/usr/include/krb5-protos.h:2387:        krb5_principal /*principal*/);
They all come from the app-crypt/heimdal-0.7.2-r3 ebuild.

These are the USE flags used for related packages:

It builds fine with mit-krb5.  I'm afraid I don't know enough about kerberos /
sasl / ... to fix this.  I would suggest you file a bug upstream.  It seems
like the autofs mailing list is the place to go.

I just worte a proposed fix for this, which I would expect to work fine for
both mit-krb5 and heimdal. There are two macros called krb5_realm_length and
krb5_realm_data provided by the heimdal headers, and matching macros are easily
provided for MIT.

Just posted there, including my patch. I hope my message gets through without
me being subscribed to the list. If it does, I'll post a reference to the
archived thread here as the URL of this issue report.

Thanks for the patch!  Now it builds with both heimdal and mit krb5.  It's been
included in autofs-5.0.3-r5.
Closing as fixed.

My original post didn't make it. Now I subscribed and reposted the issue:
