Domain name Domain Information The full name of the domain. Domain The name is used for identifying the local area network. For example, if NetBIOS name the domain name is "syno.local", the NetBIOS name is "syno". Type Distinguished name (DN) Roles Domain Controller Primary domain controller • The server that holds the PDC Emulator role and other Flexible Single Master Operation (FSMO) roles. • The PDC provides data updates if data synchronization issues occur. Secondary domain controller • The server that can hold the FSMO roles, but cannot hold the PDC Emulator role. Read-only domain controller • The server that holds a read-only copy of the domain database, replicates user account passwords according to password replication policies, and authenticates user access. • The RODC receives only replication data from RWDCs. DN is the object path of the DC in the domain database. For example, if a DC's DN is "CN=SYNOTEST,OU=Domain Controllers,DC=syno,DC=local", you can analyze its elements as below: • CN=SYNOTEST: The hostname of this DC is "SYNOTEST". • OU=Domain Controllers: The DC belongs to the organizational unit "Domain Controllers". • DC=syno,DC=local: The DC is deployed in the domain "syno.local". PDC Emulator • The PDC Emulator role holder provides time synchronization services for Kerberos authentication, recording password updates performed by other DCs within a domain. • There is only one holder of this role for each domain, and the holder must be a RWDC. 09

Emulator role.
Read-only domain controller

Distinguished
name (DN)
DN is the object path of the DC in the domain database. For example, if
a DC's DN is "CN=SYNOTEST,OU=Domain Controllers,DC=syno,DC=local",
you can analyze its elements as below:
•
CN
=SYNOTEST: The hostname of this DC is "SYNOTEST".
•
OU
=Domain Controllers: The DC belongs to the organizational unit
"Domain Controllers".
•
DC
=syno,
DC
=local: The DC is deployed in the domain "syno.local".
Roles

• The PDC Emulator role holder provides time synchronization services
for Kerberos authentication, recording password updates performed by
other DCs within a domain.
• There is only one holder of this role for each domain, and the holder
must be a RWDC.
