Claim 0:
1. A method for access control, the method comprises:
receiving, by a file server, an access request for allowing a user to access a file system entity, wherein the user is identified by a first file system protocol (FSP) user identifier that is compliant with the first FSP;
converting the first FSP user identifier to a first access control user identifier of the user, the first access control user identifier of the user represents a combination of the user and the first FSP, within the file server; wherein a size of the first FSP user identifier exceeds a size of the first access control user identifier of the user, and wherein the first access control user identifier is not compliant with the first FSP;
obtaining a multiprotocol set of access control user identifiers, based on the first access control user identifier of the user;
searching, within an access control data structure, based on the multiprotocol set of access control user identifiers, for a relevant access control rule, the relevant access control rule is associated with a member of multiple members of the multiprotocol set of access control user identifiers of the user, wherein the multiple members of the multiprotocol set of access control user identifiers of the user comprises the first access control user identifier of the user and at least one other access control user identifier of the user that represents at least one combination of the user and at least one other FSP, wherein none of the multiple members is compliant with any FSP represented by the multiple members; and
responding to the access request based on the relevant access control rule, when finding the relevant access control rule.
