Importing external LDAP users and user groups

After you complete the tasks in this section, your users will be able to log in to the SA Client with their LDAP user names and passwords.

This method does not import LDAP user groups. If you want to import users and user groups, see Importing LDAP users and user groups using LDAP authentication configuration.

To import external users with the SA Client, perform the following steps:

  1. In the SA Client navigation pane, select the Administration tab. This displays the Users and Groups node in the navigation pane.
  2. Open the Users and Groups node in the navigation pane. This displays the Users node.
  3. Select the Users node. This displays all your SA users.
  4. Select the Actions > Import Users menu. This displays information from your LDAP directory.
  5. Select the Import Users tab. This displays all the users in your LDAP directory.
  6. Select one or more users.
  7. You can optionally assign the users to one or more users groups. Select the Assign Groups tab, and select one or more user groups.
  8. Select the Import Users button. This imports the users into SA.

Importing LDAP users and user groups using LDAP authentication configuration

LDAP Authentication Configuration is a command line tool used to configure LDAP and import users and user groups into SA. This can be a complex process that requires some preparation.

Once LDAP has been configured, the LDAP Users & User Groups Synchronization APX can also be used to import LDAP users and user groups into SA.

You should not edit user groups being maintained by LDAP synchronization. These user groups are indicated by the description, __DO_NOT_EDIT__MAINTAINED_BY_LDAP_SYNC_.

See the following sections for ore information:

Prerequisites

The LDAP Authentication Configuration tool is a script that must be run on an SA Core’s Slice Component bundle host. Before running the script, you must have the following information available:

LDAP authentication configuration prerequisites

Prerequisite

Description

Hostname

Semicolon separated list of fully-qualified host name (FQHN) or IP address of the LDAP directory server that SA is to use. Only the first listed host is used for communication, the other hosts are used to handle failover scenarios.

LDAP server port

The LDAP directory server port. The default SSL port is 636 and the default non-SSL port is 389. SA does not support StartTLS.

SSL

Is SSL authentication required by your LDAP directory server? If SSL is enabled, you must supply the trusted CA certificates used to validate the server’s SSL certificate.

Trusted CA certificates to validate server SSL certificate

The complete path to the file on the LDAP directory server containing the trusted CA certificates, in PEM format, used to verify the LDAP directory server’s SSL certificate.

SSL with mutual (or two-way) authentication

You must supply the following information:

Trusted CA certificates to validate server SSL certificate

Trusted CA certificates to validate client SSL certificate

Client certificate and (unencrypted) private key.

SSL with client authentication enabled

The complete path to the file containing the trusted CA certificates, in PEM format, used to verify the SSL client certificate.

The complete path to the file containing the client SSL certificate and its corresponding private key, in PEM format. The client private key must not be encrypted.

Anonymous search to the Directory Information Tree (DIT)

Does the LDAP directory allow anonymous searches to the DIT where user information is stored? Note that this implies that anonymous bind is allowed. For example, does an anonymous user (a user who did not supply a bind DN and password) have read access to the DIT? For most enterprises, anonymous search is not allowed. If anonymous search is disabled, you must supply the bind DN and password of a user who has read access to the DIT.

Bind DN

Required only if anonymous search is disabled. The bind DN for the user who has read access to the DIT.

Bind password

Required only if anonymous search is disabled. The bind password for the user who has read access to the DIT.

Attribute for unique user name

The attribute for the unique user name.

For Active Directory, the default is SAMAccountName.

For Novell eDirectory, the default is cn.

For all other vendors, the default is uid.

Attribute for user display name

The attribute for the user display name.

For Active Directory, the default is displayName.

For Novell eDirectory, the default is fullName.

For all other vendors, the default is cn.

Base DN

The base DN, or the portion of the DIT to be considered when searching for users during the user import operation. The LDAP Authentication Configuration tool uses a subtree search; therefore, the search filter is only applicable to users at or below the base DN.

Search Filter Template

The Search Filter Template is used, with optional filter substitution, as the filter in the LDAP search for the user import.

Any dollar sign ($) character in the template is replaced by the filter string specified in the Import Users page of the SA Client. (The default value is an asterisk (*), which matches all entries.)

For Active Directory, the default is (&(sAMAccountName=$)
(objectCategory=person)
(objectClass=user)
(sAMAccountType=805306368)).

For Novell eDirectory, the default is (&(cn=$)(objectClass=person)).

For all other vendors, the default is uid=$.

LDAP authentication configuration

When you run LDAP Authentication Configuration, you will be prompted depending on whether your LDAP Directory server requires SSL authentication and whether anonymous search is allowed.

Anonymous Search: No

SSL: No

  1. Log in to a server hosting a Slice Component bundle for your SA Core.
  2. Log in as the twist user:

    su twist

  3. Issue the following command:

    cd /opt/opsware/twist

  4. Invoke LDAP Authentication Configuration:

    ./ldap_config.sh

  5. Enter the necessary information. Enter N when asked if anonymous search is allowed. Enter N when asked if SSL setup is required.
  6. After the tool completes, ensure that LDAP authentication configuration is successfully validated and stored.
  7. Log on to the Command Center and ensure that external user import works.
  8. Ensure that you can log on to the Command Center as an LDAP user.

Note: When running the ldap_config.sh script to import ldap users into a Server Automation (SA) core, with a special bind configured, the following message might appear, and the script fails:

Error: failed to verify LDAP search configuration. message=null
Failed to verify LDAP search configuration with the specified LDAP directory server.
Please correct your answers.

Additional tests with ldapsearch work, as does ldap_config.sh with a different base bind.

The error is caused when the ldap_config.sh script attempts to resolve a referral to one of the DomainDnsZones handling the bind data and encountered a timeout. Unless the script can follow the referral, it cannot validate/populate the ldap entry, resulting in the error messages.

To resolve this issue:

1. Verify that the DomainDnsZones are reachable from the core. For example, if you are trying to use a Base bind "DC=A1,DC=B2,DC=C3,DC=com", make sure that DomainDnsZones.A1.B2.C3.com:636 is reachable from the core. If it is not, check if firewalls or routers are functioning correctly.

2. If using SSL with ldap, try running ldap_config.sh without SSL. If this works, use the following command to examine the certificate returned by AD:

openssl s_client -CAfile /var/opt/opsware/crypto/twist/ldapcert.pem -connect DomainDnsZones.LA.FRD.DIRECTV.com:636

3. If non-SSL works, add the LDAP server certificate into /var/opt/opsware/crypto/twist/ldapcert.pem.

Synchronizing LDAP users

After you have completed the LDAP Authentication Configuration process, you can use the ldap_sync.sh tool to synchronize LDAP users and groups with the SA database from the command line, as described below.

You can also run the LDAP Users & User Groups Synchronization APX from the SA Client to schedule the synchronization process. This program APX (formerly named, "ldap.user_and_usergroups_sync") is listed in the SA Client under SA Library > By Type > Extensions > Program.

For instructions on running APXs, see the "Run Extensions on Managed Servers" section in the SA 10.51 Use section. This topic is also available in the SA Client help: From the list of Program APXs in the SA Client, click F1 to open the page help, then click the heading link (Extensions: Properties) to open the how-to topic.

To synchronize LDAP users and user groups using ldap_sync.sh:

On a server hosting a Slice Component bundle for your SA Core, log in as the twist user:

su twist

Issue the following command:

cd /opt/opsware/twist

Invoke LDAP synchronization:

./ldap_sync.sh

You will see output similar to the following:
