Compile error - "cannot find -lpam"

["Zhang Fei" <zhfei@sdb.ac.cn>]

Hi,all
    I have successfully installed openldap-2.0.25 in my RH7.3 box a month before, and 
am going to install the 2.1.8 version . But when I compile the 2.1.8,the following error occurs.

$./configure --prefix=/usr/local/openldap --enable-ldbm --disable-bdb --with-tls  (OK!)
$make depend              (OK!)
$make                     
..
cc -g -O2 -o apitest apitest.o  ./.libs/libldap.a /download/ldap/openldap-2.1.8/libraries/liblber/.libs/liblber.a -L/usr/kerberos/lib ../../libraries/liblber/.libs/liblber.a ../../libraries/liblutil/liblutil.a /usr/lib/libsasl.a /usr/lib/libgdbm.a -lcrypt -lpam -lssl -lcrypto -lresolv -ldl

What's mean of "-lpam"?
It's a bug?
