Safeguard Authentication Services must be able to communicate with Active Directory, including domain controllers, global catalogs, and DNS servers using Kerberos, LDAP, and DNS protocols. The following table summarizes the network ports that must be open and their function.
Table 9: Network ports
| 389 |
Used for LDAP searches against Active Directory Domain Controllers. TCP is normally used, but UDP is used when detecting Active Directory site membership. |
| 3268 |
Used for LDAP searches against Active Directory Global Catalogs. TCP is always used when searching against the Global Catalog. |
| 88 |
Used for Kerberos authentication and Kerberos service ticket requests against Active Directory Domain Controllers. TCP is used by default. |
| 464 |
Used for changing and setting passwords against Active Directory using the Kerberos change password protocol. Safeguard Authentication Services always uses TCP for password operations. |
| 53 |
Used for DNS. Since Safeguard Authentication Services uses DNS to locate domain controllers, DNS servers used by the Unix hosts must serve Active Directory DNS SRV records. Both UDP and TCP are used. |
| 123 |
UDP only. Used for time-synchronization with Active Directory. |
| 445 |
CIFS port used to enable the client to retrieve configured group policy. |
Note: Safeguard Authentication Services, by default, operates as a client, initiating connections. It does not require any firewall exceptions for incoming traffic.
Unix administration and configuration
This section explains Safeguard Authentication Services administration and configuration details relevant to administrators who are integrating Unix hosts with Active Directory.
A separate Administration Guide for macOS is available on the distribution media. While many of the concepts covered in this guide apply to macOS it is recommended that you refer to the Safeguard Authentication Services macOS Administration Guide first when working with macOS.
For full Safeguard Authentication Services functionality on Unix, you must join the Unix system on which you installed the Safeguard Authentication Services agent to the Active Directory domain. You can join an Active Directory domain either by running vastool join from the command line or the interactive join script, vasjoin.sh.
Before you join the Unix host to the Active Directory domain, you may want to determine if you are already joined.
To determine if you are joined to an Active Directory domain
- Run the following command:
# /opt/quest/bin/vastool info domain
If you are joined to a valid domain this command returns the domain name. If you are not joined to a domain, you will see the following error:
ERROR: No domain could be found.
ERROR: VAS_ERR_CONFIG: at ctx.c:414 in _ctx_init_default_realm
default_realm not configured in vas.conf. Computer may not be joined to domain
