XOCE Integration with OpenLDAP

[DustinB]

This is the most relevant information I can find regarding OpenLDAP integration for use with Xen Orchestra.

https://xen-orchestra.com/docs/ldap.html

[stormi]

@wesleylc1 you probably mean Xen Orchestra. XOCE is just a helper script from the community to install Xen Orchestra from the sources.

[DustinB]

@stormi I believe @wesleylc1 thinks you are suggesting this a script issue rather than a ldap configuration issue.

@wesleylc1 can you confirm your ldap settings from within the plugin.

[stormi]

@DustinB If that's the case, then let's state that it's not what I meant. I'm just clarifying names

[wesleylc1]

Hi @DustinB an image with the settings used by my openldap server.

@wesleylc1 the URI should look like: ldap://<ip or fqdn>

[wesleylc1]

@borzel, I made the adjustment, now a new error appears.

[borzel]

@wesleylc1 at this stage I'm out

@olivierlambert or @julien-f maybe can help.

[wesleylc1]

@borzel, thank you.

[wesleylc1]

Hello, I was able to login with my ldap login, but I would like to specify a ldap user group.

Best regards,
Wesley Santos

[olivierlambert]

So use a filter with the group you want.

[wesleylc1]

Changes made, as below.

Best regards,
Wesley Santos

[olivierlambert]

Why the group name is between < >?

[wesleylc1]

I made the changes, but I continue with errors.

Group settings in "OpenLDAP".

[olivierlambert]

I don't think that's the right syntax. But it's not a XO issue, it's a LDAP setting issue. Check what filter would work with your LDAP server, and it will work.

[borzel]

@wesleylc1 maybe the memberOf= needs a LDAP-Value like CN=blabla,OU=yadayada,DC=whatever?

[wesleylc1]

@olivierlambert
I think the error is related to the attributes of "OpenLDAP", but I'm not sure how to filter.

[olivierlambert]

You need to find/read documentation on LDAP filter for your server. Then it will work

[wesleylc1]

Dear, is it possible to search with the "group and users" option?
Best regards,
Wesley Santos

[julien-f]

@wesleylc1 As @olivierlambert said, this is an LDAP config issue, you need to know the structure of your LDAP server.

The auth-ldap plugin comes with a CLI which is useful to test various configuration and figure out what is wrong:

$ /usr/local/lib/node_modules/xo-server-auth-ldap/dist/test-cli.js
? uri
