>Description:
Due to a bug in Cyrus IMAPd's configure script GSSAPI/krb5 support is
not built correctly, at least not on a NetBSD 3.1 system using its
native Heimdal libraries.
>How-To-Repeat:
Using Cyrus IMAPd's krb5 authorisation module, try to use a Kerberos
V principal with an instance (e.g. user/admin@REALM) and notice imapd
logging

badlogin: [...] GSSAPI [SASL(-13): authentication failure: bad userid 
authenticated]

While building mail/cyrus-imapd, see configure correctly detecting
gssapi.h:

[...]
checking gssapi.h usability... no
checking gssapi.h presence... no
checking for gssapi.h... no
checking gssapi/gssapi.h usability... yes
checking gssapi/gssapi.h presence... yes
checking for gssapi/gssapi.h... yes
[...]
checking for gss_unwrap in -lgssapi... yes
checking GSSAPI... with implementation heimdal
[...]

but then inspect config.h and notice HAVE_GSSAPI_H not being defined...

Read this for more details:
http://thread.gmane.org/gmane.mail.imap.cyrus/24605/focus=24605
>Fix:
Defining HAVE_GSSAPI_H also if .../gssapi/gssapi.h was found seems to
fix the problem:
