Outline of the configuration items

'auth_ldap_context' => 'ou=people,dc = example, dc = com',# LDAP context to link.

'auth_method_1' => 'ms-ldap', #First type of Authentication can be followed by other types

'auth_ms_ldap_attr' => 'sAMAccountName',# the attribute that matches the username.

'auth_ms_ldap_base' => 'dc=corp, dc=example,dc=com',#base to search in LDAP

'auth_ms_ldap_dn_acc' => 'CN=omklatam, ou = Services, dc = OPMANTEK, dc = corp', #

'auth_ms_ldap_dn_psw' => 'password,',

'auth_ms_ldap_server' => 'host_LDAP: 389',


Aspects to consider:


Info
titleNOTE on MS-LDAPS SSL

To use SSL/TLS secured MS-LDAP (MS-LDAPS) see the differences in the table in User Management in NMIS8 .

In summary it requires Optional Perl Modules: IO::Socket::SSL and Net::LDAPS and uses config items:
'auth_method_1' => 'ms-ldaps'
'auth_ms_ldaps_server' => 'host[:port]'    (note the s at the end of ldaps vs ldap)

If you use an internal CA for your AD LDAP SSL certificates you will need to import your internal root CA public certificates so that SSL can trust the connection.  Search processes for your NMIS servers OS.


LDAP Base: The base is the root of the Active Directory, since it is the place where the search of the users who need to authenticate will be carried out.Taking as reference the structure of the Active Directory will be as follows: 

'auth_ms_ldap_base' => 'dc = OPMANTEK, dc = corp',#base to search in LDAP

'auth_ldap_context' => 'dc = OPMANTEK, dc = corp',# LDAP context

The account is the service account which user is going to authenticate with the active directory, to enable the search of the LDAP Database for users. 

Therefore, the first part is added is the service account username CN=omklatam

The second part is the OU = Servicescontainer. 

The third part is the domain DC = OPMANTEK and DC = corp.

The result would be the following: 

'auth_ms_ldap_dn_acc' => 'CN = omklatam, ou = Services, dc = OPMANTEK, dc = corp',


To find the user and group base DN, run a query from any member server on your Windows domain:

Finding the User Base DN

    1. Open a Windows command prompt.

    2. Type the command:

      Code Block
      dsquery user -name <known username>


      Example: If you are searching for all users named "John", you can enter the username as John* to get a list of all users who's name is John.

      The result will look like:


      Code Block
      "CN=John.Smith,CN=Users,DC=MyDomain,DC=com"



Installation and configuration.


  • Make sureNet :: LDAP is up to date (minimum version 0.64).

[root @ opmantek] #cpan Net :: LDAP

  • Make sure that IO :: Socket :: SSLis new enough (must be 1998 or newer).

[root @ opmantek] #cpan -f IO :: Socket :: SSL

Note:-f is because some tests do not pass on some machines.
