http://www.symantec.com/docs/TECH104726

Hello,

It is possible , the above links will help you to achieve the authentication using AD/LDAP. First you need to configure the directory server.

Hi AJ,

Refer the below Steps for AD:

1. In the Symantec Endpoint Protection Manager console, click Admin.

2. In the Admin page, under Tasks, click Servers.
3. In the Admin page, under View Servers, select the Symantec Endpoint Protection Manager to which you want to add a directory server.
4. In the Admin page, under Tasks, click Edit Server Properties.
5. In the Server Properties for name of site dialog box, click Directory Servers.
6. In the Server Properties for name of site dialog box, click Add.
7. In the Add Directory Server dialog, type the name for the directory server (domain name) that you want to add in the Name field.
8. In the Add Directory Server dialog, check Active Directory as the Server Type.
9. In the Add Directory Server dialog, type the IP address, host name, or domain name in the Server IP Address or Name field. You must type the IP address, host name, or domain name of the Directory Server that you want to add.
10. Type the user name of the authorized directory server account in User Name field.
11. Type the password for the Directory Server account in the Password field.
12. Click OK.
13. When you click OK, SEPM will test the connection with the added server, if anything is wrong, the test will fail & will give you an error message: "The server failed to connect to the target directory server".
14. Check your configuration and try again till it comes without an error.

Please do the following:

Step A - Add the Active Directory Server to the SEPM:

1. Login to the SEPM
2. Click Admin > Servers
3. Right-click your SEPM's name (top-left)
4. Click Edit Properties
5. Click Directory Servers > Add
6. Enter a name to identify your Active Directory server
7. Select Active Directory next to Server Type
8. Enter the Active Directory server hostname or IP address
9. Enter a username and password that the SEPM can use to communicate with the Active Directory server
10. Click OK. The SEPM will test the Directory Server information which was entered to confirm it works properly.

Step B - Create a new SEPM Administrator account:

1. Login to the SEPM
2. Click Admin > Administrators > Add Administrator
3. Enter a username for the new administrator account. This will be the username used to login to the SEPM.
4. Enter a full name for the new administrator account. This is used for informational purposes only.
5. Leave the Password and Confirm Password fields blank
6. Click Change
7. Select Directory Authentication
8. In Directory Server, select the Active Directory server configured in Step A-6
9. In Account Name, enter the account name as it appears in Active Directory
10. Click OK
11. Click OK

Test the newly created account:

1. Logoff the SEPM if logged in
2. Use the username entered in Step B-3. Usernames are case sensitive.
3. Use the Active Directory password for the Active Directory account specified in Step B-9.
4. Leave the Domain field blank. (This field expects a SEPM domain and not an Active Directory domain)

CAUTION:
Do not use the built-in SEPM account "admin" for Active Directory Authentication. Doing so can prevent access to the SEPM if the Active Directory server is ever decommissioned, unreachable, or moved.

SEPM Active Directory Authentication is only supported for administrator accounts that have been created in SEPM by clicking "Add Administrator."
