LDAP problems with "allow bind_v2"

[Octavio Ramirez Rojas <Octavio.Ramirez@prism.uvsq.fr>]

Hi, 

I working under linux mandrake 9.0, i installed OpenLdap 2.0.21

Into "slapd.conf" file I added the instruction "allow   bind_v2" like
this:

database        bdb
suffix          "dc=prism,dc=fr"
rootdn          "cn=Manager,dc=prism,dc=fr"
rootpw          secret
directory       /usr/local/var/openldap-data
index   objectClass     eq
allow   bind_v2

but, i have this error:

[root@azteca libexec]# ./slapd -d6
daemon_init: <null>
daemon: socket() failed errno=97 (Address family not supported by
protocol)
bdb_initialize: Sleepycat Software: Berkeley DB 4.1.25: (December 19,
2002)
bdb_db_init: Initializing BDB database
/usr/local/etc/openldap/slapd.conf: line 71: allow line must appear
prior to database definitions
bdb_db_open: dc=prism,dc=fr
slapd starting

------

I moved the "allow line", but i have the same error.

regards

Octavio
