revokeRolesFromUser

Removes a one or more roles from a user on the database where the roles exist. The revokeRolesFromUser command uses the following syntax:

{ revokeRolesFromUser: "<user>",
roles: [
{ role: "<role>", db: "<database>" } | "<role>",
...
],
writeConcern: { <write concern> },
comment: <any>
}

The command has the following fields:

Field
Type
Description
revokeRolesFromUser
string
The user to remove roles from.
roles
array
The roles to remove from the user.
writeConcern
document
Optional. The level of write concern for the modification. The writeConcern document takes the same fields as the getLastError command.
comment
any

Optional. A user-provided comment to attach to this command. Once set, this comment appears alongside records of this command in the following locations:

A comment can be any valid BSON type (string, integer, object, array, etc).

New in version 4.4.

In the roles field, you can specify both built-in roles and user-defined roles.

To specify a role that exists in the same database where revokeRolesFromUser runs, you can either specify the role with the name of the role:

"readWrite"

Or you can specify the role with a document, as in:

{ role: "<role>", db: "<database>" }

To specify a role that exists in a different database, specify the role with a document.

You must have the revokeRole action on a database to revoke a role on that database.

The accountUser01 user in the products database has the following roles:

"roles" : [
{ "role" : "assetsReader",
"db" : "assets"
},
{ "role" : "read",
"db" : "stock"
},
{ "role" : "readWrite",
"db" : "products"
}
]

The following revokeRolesFromUser command removes the two of the user's roles: the read role on the stock database and the readWrite role on the products database, which is also the database on which the command runs:

use products
db.runCommand( { revokeRolesFromUser: "accountUser01",
roles: [
{ role: "read", db: "stock" },
"readWrite"
],
writeConcern: { w: "majority" }
} )

The user accountUser01 in the products database now has only one remaining role:

"roles" : [
{ "role" : "assetsReader",
"db" : "assets"
}
]
