getaddrinfo failed with -lbind and peter.marschall-011029.patch do not work

[罗志坚 <luozhijian@huawei.com>]

I am install openldap 2.20 in suse9+sp1(SUSE LINUX Enterprise Server 9 (i586) - Kernel 2.6.5-7.139-smp (1).)

make test failed,log show me "slap_get_listener_addresses: getaddrinfo ai_addr is NULL?"

then I search in openldap.org and found peter.marschall-011029.patch can fix this problem,
but patch failed:
<179 [lzjian] :/home/lzjian/src/openldap-2.2.20> patch -p0 < peter.marschall-011029.patch

Hunk #1 FAILED at 273.

2 out of 2 hunks FAILED -- saving rejects to file servers/slapd/daemon.c.rej

patch is provided in 2001,code change a lot.so I modify daemon.c by manual.but it didn't work.

I trace daemon.c with gdb,I found sai->ai_addr is null when host is not null,so the patch didn't work.

peter.marschal-011029.patch:
-   if( sai->ai_addr == NULL ) {
+   if( sai->ai_addr == NULL && host != NULL) {

My question£º
1¡¢Can anyone help me fix this problem?

2¡¢If I remove lib of bind,it can pass "make test".but will openldap work well?
