Why the group name is between < >?

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?

@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

Dear @julien-f ,

I was able to perform the integration with "OpenLDAP", but I can not apply the filter using "" memberOf "", I could identify, the filter does not occur because my "LDAP" uses old parameters, filters using the "memberUid" attribute. You have some examples of how I can apply to filter group users with the "memberUid" attribute.

Best regards,
Wesley Santos

julien-f

@wesleylc1 It really depends of the structure of your LDAP server.

I've just committed a new version of the plugin which makes the test CLI displays the matched entry on success, this helps figuring out what should be put in the filter field.

Example:

$ xo-server-auth-ldap
? uri ldap://ldap.company.net
? fill optional certificateAuthorities? No
? fill optional checkCertificate? No
? fill optional bind? No
? base ou=people,dc=company,dc=net
? fill optional filter? No
configuration saved in ./ldap.cache.conf
? Username john.smith
? Password [hidden]
searching for entries...
.
1 entries found
attempting to bind as uid=john.smith,ou=people,dc=company,dc=net
successfully bound as uid=john.smith,ou=people,dc=company,dc=net => john.smith authenticated
{
  "messageID": 1,
  "protocolOp": "SearchEntry",
  "objectName": "uid=john.smith,ou=people,dc=company,dc=net",
  "attributes": [
    {
      "type": "cn",
      "vals": [
        "John Smith"
      ]
    },
    {
      "type": "gidNumber",
      "vals": [
        "10000"
      ]
    },
    {
      "type": "givenName",
      "vals": [
        "John"
      ]
    },
    {
      "type": "homeDirectory",
      "vals": [
        "/home/john.smith"
      ]
    },
    {
      "type": "initials",
      "vals": [
        "JSH"
      ]
    },
    {
      "type": "loginShell",
      "vals": [
        "/bin/bash"
      ]
    },
    {
      "type": "mail",
      "vals": [
        "john.smith@company.net"
      ]
    },
    {
      "type": "objectClass",
      "vals": [
        "posixAccount",
        "inetOrgPerson",
        "organizationalPerson",
        "person"
      ]
    },
    {

        "Smith"
      ]
    },
    {

      "vals": [
        "john.smith"
      ]
    },
    {
      "type": "uidNumber",
      "vals": [
        "10000"
      ]
    }
  ],
  "controls": []
}

@julien-f With this test option would be perfect to find out which filter should I use, how do I update to this version of the plugin?

? uri 192.168.XX.XX
? fill optional certificateAuthorities? No
? fill optional checkCertificate? No
? fill optional bind? No
? base ou=BH,o=PRJ,c=BR
? fill optional filter? No
configuration saved in ./ldap.cache.conf
? Username cn=adm,c=br
? Password [hidden]

It depends how you installed it, unfortunately I cannot help you for this.

Once you've upgrade to the latest version, use the default filter to authenticate the user and then you will see what fields it contains, then you will be able to write the correct filter.

wesleylc1

@julien-f @DustinB

I performed the installation through the link below.

https://github.com/Jarli01/xenorchestra_installer

the version of the updated plugin is already available in the Jarli repositories?

Best regards,
Wesley Santos

wesleylc1

@julien-f Can you list what types of filters are supported by the plugin?

julien-f

@wesleylc1 I'm not an expert, but it's a standard LDAP filter which is evaluated by the LDAP server, no special handling is done by the plugin itself.

wesleylc1

@julien-f How can I download the new version of the plugin, according to the output below, I can not automatically query the filters through the script "/test-cli.js".

? uri ldap://192.168.xx.xx
? fill optional certificateAuthorities? No
? fill optional checkCertificate? No
? fill optional bind? Yes
? bind > dn cn=admin,c=br
? bind > password  XXXX
? base ou=XX,o=PRJ,c=BR
? fill optional filter? Yes
? filter (&(cn=gp-ti-infra)(memberUID={{name}}))
configuration saved in ./ldap.cache.conf
? Username user01
? Password [hidden]

julien-f

@wesleylc1 For the upgrade, you need to ask the people behind the install script you used.

Concerning the output, it will only show the entry if the authentication was successful, that's why you need to start by using the default filter.

wesleylc1

The default filter is (uid = {{name}})?

wesleylc1

@julien-f the filter "(& (cn = gp-ti-test) (memberUID = {{name}}))" is to release access to users of a group but "bind as" is not being mounted as it should

? uri ldap://192.168.XX.XX
? fill optional certificateAuthorities? No
? fill optional checkCertificate? No
? fill optional bind? Yes
? bind > dn cn=adm,c=br
? bind > password *****
? base ou=BH,o=PRJ,c=BR
? fill optional filter? Yes
? filter (&(cn=gp-ti-teste)(memberUID={{name}}))
configuration saved in ./ldap.cache.conf
? Username user1
? Password [hidden]
