box.schema.user.revoke()

object-name[, {options} ]) box.schema.user.revoke(username, permissions, 'universe'[, nil, {options} ]) box.schema.user.revoke(username, role-name[, nil, nil, {options} ])

Revoke privileges from a user or from another role.

Parameters:

• username (string) — the name of the user

• permissions (string) — one or more permissions to revoke from the user (for example, read or read,write)

• object-type (string) — a database object type to revoke permissions from (for example, space, role, or function)

• object-name (string) — the name of a database object to revoke permissions from

• options (table) — if_exists

The user must exist, and the object must exist, but if the option setting is {if_exists=true} then it is not an error if the user does not have the privilege.

Variation: instead of object-type, object-name say 'universe' which means 'all object-types and all objects'.

Variation: instead of permissions, object-type, object-name say role-name (see section Roles).

Variation: instead of box.schema.user.revoke('{username}','usage,session','universe',nil, {if_exists=true}) say box.schema.user.disable('{username}') (see section box.schema.user.disable).

Example:

 
box.schema.user.revoke('testuser', 'write', 'space', 'books')        box.session.su('testuser')        local _, delete_book_error = pcall(function()            box.space.books:delete(10)        end)        t.assert_equals(delete_book_error:unpack().message, "Write access to space 'books' is denied for user 'testuser'")        box.session.su('admin')        -- Revoke session --        box.schema.user.revoke('testuser', 'session', 'universe')        -- End: Revoke session --        local _, change_user_error = pcall(function()            box.session.su('testuser')        end)        t.assert_equals(change_user_error:unpack().message, "Session access to universe '' is denied for user 'testuser'")    end)endg.test_user_dropped = function(cg)    cg.server:exec(function()        box.schema.user.create('testuser')        -- Drop a user --        box.schema.user.drop('testuser')        -- End: Drop a user --        t.assert_equals(box.schema.user.exists('testuser'), false)    end)end
