Как в ядре включить опцию "NDS authentication support". Ее там посто нет. Эта опция нужна для монтировани томов NetWare. В документации сказано: For full NDS support (background authentication) you must enable 'NDS authentication support' in kernel configuration. This option is available only in 2.[34].x kernels. In 2.2.x kernels you can make option available by simple uncommenting this option in linux/fs/ncpfs/Config.in (option is commented out because of at the time 2.2.0 was released there was no userspace support). If you have older kernel, you should upgrade if you need such support.
Но в linux/fs/ncpfs/Config.in нет тако опции не закомментированно, не раскомментированной. У меня RH7.3 (ядро 2.4.22)
