Hi,

I have the same problem. Everything was working great but since last 2 weeks I have been receiving this error When i click some menus like Network Map, Accounts/users ...
MS AD connects successfully but i think I cannot get a some kind of connection or something blocks. I did a little bit research that i could find this error below. I am not sure it's related to or not. is there anyone to give me a clue to fix this?

Hello Cumhur,
Can you look back in your yum log and see if the issue was related to the 7.4 update? The update would have happened automatically on or around 20th Oct, but if you are updating manually, could have happened later. Do you have a folder /etc/openldap/slapd.d? If so, you have hit a rare bug and the fix is here. If you do believe this is the issue and don't feel confident of following the instructions, you are welcome to raise a support ticket for free (raise it as a General Enquiry).

Hi;

automatically update is enabled and I do not have a folder /etc/openldap/slapd.d. I did not understand that how to raise it as a General Enquiry? You mean can iopen a free tickedt in Generel category?

Thanks in advance...

Unfortunately if you do not have the folder /etc/openldap/slapd.d then it is not the same issue as I linked to and you don't qualify for the free support offer.

If you start LDAP manually ("service slapd start"), do you see any errors? Also is there anything in the logs?

What is the contents of /etc/clearos/network.conf and the output of "ls /sys/class/net"?

Hi;

All outputs of you asked me is here. I am not expert of ClearOS or linux. So I really do not know where to start. If you can see any clue maybe you can say that where to start.
Thanks for the help Nick.

Guessing here. Is one of your WAN interfaces unconfigured? If so, please try changing it to LAN and give it a fixed IP on a different subnet from ens32.

[edit]
In your Directory Server app, what is your Publsh Policy?
[/edit]

Thanks for the reply Nich,

Please find my ifconfig result. I am not sure how to find misconfigured WAN connection in ClearOS . For example you means that ens35 WAN connection IP address should be the same n my LAN IP block? like 192.168.2.5 but subnet should be 255.255.254.0?

Also How can i find my Publish Policy in Directory Server App? which menu I have to follow?

Your configuration looks OK.

The Directory Server app is Webconfig > Server > Directory > Directory Server but I don't think there will be any issue there.

When it fails to start, is there anything in /var/log/messages or /var/log/system which gives any indication of an issue.

Hi,

I tried with tail -f and then The only think i see is below I think I need to reconfigure or reinstall this even If I do not know It's possible but I do not know where to look anymore?
is it possible to put back /etc/openldap/slap.d from somwhere?

Searching old posts, can you start ldap with:

/usr/sbin/slapd -h 'ldap://127.0.0.1/ ldaps://127.0.0.1/' -u ldap -d -1

Look for error messages and check your logs afterwards.

Don't worry about /etc/openldap/slap.d not existing. It should not. If it did, it is an indication of another issue.

/usr/sbin/slapd -h 'ldap://127.0.0.1/ ldaps://127.0.0.1/' -u ldap -d -1

Here is the output

I think there is some kind of misconfigured settings or

What is the output of:

netstat -peanut | grep LIST | egrep "389|636"

It is strange when it says the address is already in use.

Here is the results I think my LDAP I mean Domain Controller IP is 192.168.2.8.
fist ip (192.168.2.1 is wrong i think?

[root@gateway ~]# netstat -peanut | grep LIST | egrep "389|636"

[root@gateway ~]#

Odd. That says LDAP is already running. It is listening for ldap and ldaps on localhost and ldaps on your LAN interface.

Have I misunderstood something as I am not familiar with the AD connector set up? Is it worth rebooting the server at this point? Alternatively you can try a "service slapd stop" and see if 'netstat -peanut | grep LIST | egrep "389|636"' then shows nothing, then restart it. Or do a "ps aux | grep slapd" and kill any process, before restarting slapd. I'd prefer the reboot.
