Problem in LDAP
 
Assalam o Alaikum!

I have followed following link for configuring LDAP. But I am unable to login from client to ldap server.
Server
http://www.server-world.info/en/note..._14&p=ldap&f=1
Client:
http://www.server-world.info/en/note..._14&p=ldap&f=2

Now I when I tried from client in this way at login screen:
uk.example.com
Password:******
Authentication fails

tcpdump result at server side:

03:24:10.542392 IP 192.168.1.93.59277 > server.example.com.ldap: Flags [S], seq 2995702033, win 5840, options [mss 1460,sackOK,TS val 4604901 ecr 0,nop,wscale 6], length 0

you've jumped far too many steps there. Can you bind to ldap with a valid account with ldapsearch? A basic tcpdump is of no use other than to show that there is ldap communication happening, which is certainly something. You should really look at that traffic in wireshark and look at the actual LDAP requests being made, that's extremely useful.

Hi,

Check in slapd.conf ,whether you are using any encrypted algorithm for storing password for your LDAP Directory manager.

Also try to connect locally first rather than checking tcpdump output...in case if ssh is not enabled you will not be able to connect to server remotely.

LDAP provides simple bind to connect to LDAP Server...

What would SSH have to do with any of this?

[root@fedora14 client]# ldapsearch -h ukengr
ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1)

my distro is fedora 14

acid_kewpie 10-16-2012 07:05 AM

well from that you need to learn how to do an ldapsearch. plenty of docs and examples out there. immediately, you would want to add an -x to do a "normal" bind instead of SASL

Please provide me any link for configuring LDAP for fedora 14+,

When I googled I found mostly links for less than fedora 14.

I am confused when I see configuration related to fedora 12 or 13 their config files naming and config is little bit different. example in fedora 14 config file name is ldap.conf and in fedora 13 it is slapd.conf.

It may be childish question above. But I need to clear this concept please help. Thanks

acid_kewpie 10-17-2012 06:38 AM

you're reading the wrong docs and haven't covered the advice you've already been given. slapd.conf is for an OpenLDAP server, not OS level LDAP client config. Newer versions of Fedora will be using nslcd.conf but not in 14 I don't believe (which is obsolete)
