Windows to UNIX name mapping fails if:
- The Windows and UNIX user names contain uppercase characters
- There are no explicit name-mapping rules defined for the win-unix direction.
If a default UNIX user is defined in CIFS options (such as pcuser), the mapping will be shown as 'pcuser' when running diag secd authentication show-creds. If no default UNIX user is defined in CIFS options, errors similar to the following might be reported:
Filer::*> diag secd authentication show-creds -node Filer-01 -vserver testsvm -win-name TestUser
Vserver: testsvm (internal ID: 11)
