You should be aware of the following when using Samba to access NSS volumes on an OES 11 SP3 server.
If you will have more than 2,000 files and folders accessed through Samba, you should consider using NSS as the underlying file system. Above that number, Samba on NSS outperforms Samba on traditional Linux volumes, such as Ext3, ReiserFS, or XFS. As you add more files and directories above the 2,000 mark, the performance advantage increases.
Samba-enabled users cannot access an NSS volume using Samba until they are granted NSS trustee rights to the files and directories on that volume. Rights are automatically granted for home directories on NSS volumes that are created in iManager. For other work directories that you want to set up as Samba shares, you must grant users the appropriate access rights.
OES 11 SP3 provides numerous tools for granting NSS trustee rights to users and groups. For more information, see Section 8.5, Typical Samba Configuration Scenarios.
Because Windows is case insensitive, it is recommended that NSS volumes be mounted as case insensitive (Lookup Namespace set to Long) when they are to be accessed through Samba.
