Security Role Requirements for Replication

Replication restricts the specific actions that a user can perform based on the roles to which the user's login is mapped. Replication has granted certain permissions to the sysadmin fixed server role, the db_owner fixed database role, and the logins in the publication access list (PAL).

The following table summarizes the authentication level necessary for common replication setup tasks:

Setup task Membership requirement

Enable a Distributor, Publisher, or Subscriber.

sysadmin server role on the Publisher.

Enable a database for replication.

sysadmin server role on the Publisher.

Create a publication.

db_owner database role on the publication database at the Publisher or sysadmin server role on the Publisher.

View publication properties.

Member of the PAL at the Publisher, db_owner database role on the publication database at the Publisher, or sysadmin server role on the Publisher.

Create a subscription.

db_owner database role on the publication database at the Publisher or sysadmin server role on the Publisher.

db_owner database role on the subscription database at the Subscriber or sysadmin server role on the Subscriber.

Configure agent profiles.

sysadmin server role on the Distributor.

The following table summarizes the authentication level necessary for common replication maintenance tasks:

Maintenance task Membership requirement

Modify or drop a Distributor, Publisher, or Subscriber.

sysadmin server role on the appropriate server.

Modify or drop a publication.

db_owner database role on the publication database at the Publisher or sysadmin server role on the Publisher.

Modify or drop a subscription at the Publisher.

db_owner database role on the publication database at the Publisher or sysadmin server role on the Publisher.

Modify or drop a subscription at the Subscriber.

db_owner database role on the subscription database at the Subscriber or sysadmin server role on the Subscriber.

Mark a subscription for reinitialization.

Push subscription: db_owner database role in the publication database at the Publisher or sysadmin server role on the Publisher.

Pull subscription: db_owner database role in the subscription database at the Subscriber or sysadmin server role on the Subscriber.

View replication activity, errors, and history using Replication Monitor. A user cannot modify agent profiles, schedules, and so on, unless the user is a member of the sysadmin server role.

replmonitor database role on the distribution database at the Distributor or sysadmin server role on the Distributor.

Maintain replication agents.

db_owner database role in the appropriate database or sysadmin server role on the appropriate server.

If the agent was created by a user in the sysadmin role, and a proxy account was not specified for the agent, the agent runs under the context of the SQL Server Agent account. In this case, a user in the db_owner role cannot modify the job associated with the agent.

Start or stop a replication agent.

Owner of the agent job or sysadmin server role on the appropriate server.
