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 2 Linux 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 10 SP1 and later update channels. For 32-bit OES 2 Linux and later, it is okay to accept Samba updates separately. However, 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.
