[Mimedefang] Compiling MimeDefang 2.72 (configuration bug report).

For some reason, MD 2.72 didn't pick up that it needed the LDAP library (i.e. a "-lldap" added to the compiling line, when libmilter also has LDAP enabled).

gcc -g -O2 -Wall -Wstrict-prototypes -pthread -o mimedefang mimedefang.o drop_privs_threaded.o utils.o rm_r.o syslog-fac.o dynbuf.o milter_cap.o gen_id.o -L../sendmail-8.14.5/obj.Linux. -lmilter -lpthread -lnsl 
../sendmail-8.14.5/obj.Linux. In function `sm_errstring':
errstring.c:(.text+0x482): undefined reference to `ldap_err2string'
collect2: ld returned 1 exit status
make: *** [mimedefang] Error 1

I saw no check for LDAP support during the configure stage either.

I use openldap, installed with this shell script:

configure --prefix=/usr --enable-ipv6 --enable-shared --enable-threads --disable-backends --enable-bdb --enable-ldap --enable-sql --with-slapd --without-slurpd --without-ldapd
SLAPD_USE_SQL=mysql make sql
exec make depend all install

Sendmail (and thus the milter library) is built with these M4 options:

APPENDDEF(`confLIBS',`-lcrypto -lldap -lpthread -lssl -lsasl2 -ldb')

Adding the missing "-lldap" to that one compile allows me to complete and install MD (and I have done so).  Maybe autoconf needs to be alerted that the LDAP library needs to be linked in as the milter library may be dependent on it.
