Cross-protocol locking allows CIFS users to concurrently access files along with NCP users by allowing only one user at any time to open the file for write. Multiple users who are accessing via these protocols can open a file for read only.
WARNING:Allowing users who access files via different protocols to concurrently open a file for write can lead to data corruption.
NCP Server for Linux provides cross-protocol locking for NCP users and CIFS users. OES CIFS supports cross-protocol locking to coordinate with NCP.
