have you indexed the database ?
index   default                                                sub
index   uid,mail                                               eq
index   cn,sn,givenName                                        eq,sub
index   objectClass                                            pres,eq
index   uidNumber,gidNumber,memberuid                          eq

and slapindex


 And filtered ldap queries ? eg. :
pam_login_attribute     uid
pam_filter              objectclass=posixAccount
                                                                                
nss_base_passwd         ou=People,dc=server,dc=maison
nss_base_shadow         ou=People,dc=server,dc=maison
nss_base_group          ou=Group,dc=server,dc=maison
, in /etc/ldap/ldap.conf)

I can even use john the ripper now.

Btw i d be glad if nscd or slapd could have a workaround to avoid this "infinite" loop ... maybe a default safe mimit setting on simultaneous ldap queries ?
