nss_ldap: failed to bind to LDAP server ldap://127.0.0.1: Can't contact LDAP server

Hi all,

I'm playing with a redhat enterprise 4  that uses ldap, since a few days i've notice that the slapd daemon is not able to bind to the default port 389, i'm very new to this server so i could being doing something of very stupid!

[root@ myserver etc]# netstat -tuan | grep 389
[root@ myserver etc]# 

i was wondering if a run time file of the server hasn't been properly removed due to a brutal restart, and now the process isn't able to bind to any port, does that make sense? which files should i look for?

[root@ myserver etc]# ls /var/run/openldap/
[root@ myserver etc]# ls /var/lock/
dmraid  lvm  rpm  subsys
[root@ myserver etc]#

i've tried to reinstall/downgrade various packages but nothing:

[root@ myserver etc]# rpm -q openldap
openldap-2.2.13-12.el4_8.2
[root@ myserver etc]# rpm -q openldap-servers
openldap-servers-2.2.13-12.el4_8.2
[root@ myserver etc]# rpm -q openldap-clients 
openldap-clients-2.2.13-12.el4_8.2
[root@ myserver etc]# rpm -q nss_ldap
nss_ldap-253-7.el4
[root@ myserver etc]#

thank you very much for some help!! i don't know where too look anymore, i've installed the same package on another redhat enterprise 4 and it correctly binds the default port, i'm thinking to move temporarily the ldap database on the other server which should be:


1) cp /usr/lib/ldap

2) cp configuration files

3) configure web application to use the new slapd server

am i missing something ? thanks !

p.s. i've been googling around and there is something but no results : (
