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).

Security Role Requirements for Replication Setup

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.
