NCP uses the sambasharemodes.so library file to support the cross-protocol file locking capability that coordinates access to files by NCP users and CIFS/Samba users. NCP updates that are released through the OES 2015 SP1 and later update channels and in support packs include the sambasharemodes.so library file that you need for NCP. Patches for Linux Samba are also released separately through the SUSE Linux Enterprise Server 11 SP2 and later update channels. For 64-bit OES 2 Linux and later, there is a risk of breaking the cross-protocol locks functionality if the sambasharemodes.so library file is modified from the version released with NCP.
