- The included script fails to shut down saslauthd properly
- Kerberos plugin is not compiled
- The configuration script links with the installed Berkeley DB with highest version,
  even when other headers are included
- Berkeley DB 4.1 support is broken

Fix: The following patch fixes:
- path to pid
- choose the right Berkeley DB version (hack)

It disables Kerberos and Berkeley DB 4.1 until these issues have been investigated further.

cd /usr/ports/security
patch < ~/cyrus-sasl-2.1.3_1.patch
find cyrus-sasl2 -name '*.orig' -delete
How-To-Repeat: 
- The script assumes the daemons pid is in /var/state/saslauthd/mux.pid
  instead of /var/state/saslauthd/saslauthd.pid

- The configuration script fails to detect libkrb, do 'make' and the look in ${WRKSRC}/config.log:

configure:4934: checking for krb_mk_priv in -lkrb
configure:4953: cc -o conftest -Wall -W -Wall -O -pipe -L/usr/local/lib -R/usr/local/lib  conftest.c -lcrypto -lcrypt -lkrb -lcom_err  1>&5

- Install Berkeley DB 4.0 and then choose Berkeley DB 3.0 in the installation.
  The libraries are compiled with -I/usr/local/include/db3 and -ldb4.
  That happened even before the patch in ports/50962.

- sasldb works with Berkeley DB 3.3 and 4.0, but with 4.1 I get:

error fetching from sasldb: Invalid argument
error closing sasldb: Invalid argument

  in /var/log/messages. Probably something in sasldb/db_berkeley.c.
