NetWare SFTP can't navigate the file system or see some paths

NetWare file systems use a concept called "visibility rights" to allow users to see paths leading to locations where they have effective rights. For example, if user "bob" has effective rights (either explicit or inherited) to vol1:users\home\bob, then bob should be able to CD to the root directory of vol1, and see that a subdirectory called 'users' exists. Even though bob does not have a explicit or inherited trustee assignment at vol1:\ or at vol1:\users\, he has visibility rights so he can see the path that leads to the locations of his actual rights.

SFTP sessions have not been successfully getting visibility rights, which interferes with their ability to see some paths and navigate around the file system. This issue was tracked to a LIBC.NLM problem.
