No base DN created during LDAP setup

Hi,

In step 6, on the "Manage Schemas" page there are no checkboxes, just the name of the schema, its description, and "view" and "edit" links but no way to "select" a schema. Also, I did apply the configuration in step 8 but never got prompted to create the root DN in step 9.

However, I was able to get the root DN created by following the external guide located at http://www.learnitguide.net/2016/01/configure-openldap-server-on-rhel7.html. I didn't go through the whole thing, just to the part where you have to create the base.ldif file and add it to the database, but the only part of that file I used was the root DN part, not any of the users or etc. because I want to continue following the Virtualmin guide in the "Creating LDAP Trees" section.

I'll keep following the guide and let you know if I run into any more errors; the "Browse Database" page now correctly shows my root Dn instead of giving me the "no such object" error.

Thanks, -Logan

I followed the rest of the Setting Up LDAP guide without any further issues and now have one LDAP server and three client nodes. So I guess the issue with the base DN not being created automatically by Webmin was the only one I had while setting up LDAP, and I resolved it by manually creating the DN. However, please do let me know if you figure out the cause of the issue as it would be nice if Webmin could once again create the base DN for me automatically.

Hi,

So my LDAP server is properly configured, at least reported by Webmin/Virtualmin, and I can properly use the LDAP Users and Groups module to create new user and group accounts without any issues whatsoever.

However, when I go to create a new virtual server, I get the following error at the very top: failed to create administration group [GROUPNAME]: group created but does not exist.

There was about a 10-second pause from when it started creating the group to when it failed with that error message.

I have checked and double-checked my configuration both on the server and client, and have completely disabled NSCD (systemctl stop nscd && systemctl disable nscd) on both the server and client, and have rebooted each machine, but still get this problem.

This looks like the last issue I would have with this as everything else in Virtualmin is configured and ready to start creating virtual servers.

Do you know how I could resolve this issue?

Thanks, -Logan

A quick update: when running ldapsearch on the server to show all accounts and attributes and etc., it seems the "example" user created by Webmin while following the documentation is correctly placed in the "Users" DN but when using the Webmin LDAP Users and Groups module on the client to create a test user, the user gets created but is not placed into the Users DN and cannot log into the server via SSH or through su. Not sure if this is an intentional issue or not....

One more update and new issue: I fixed the earlier issue where Virtualmin created the administration group but it did not exist. I can't remember exactly how I fixed it, I essentially just reconfigured the LDAP Client module, checked /etc/nslcd.conf, converted the old config file format Webmin used to the new format NSLCD expects, and restarted everything.

Now, everything works except creating mail aliases. Here is the output of the Create Virtual Server operation for context, notice the failures with mail aliases and the like:

Do you have any suggestions for where to look for this? Unfortunately it doesn't tell me the exact syntax error, just that there is "invalid syntax."

Thanks, -Logan

Fixed it! Turns out I forgot to go into the Postfix module and configure object attributes and etc. as mentioned in the documentation. So now everything in Virtualmin works properly. :)
