secd authentication show-creds

Error: Get user credentials procedure failed [ 0 ms] Determined UNIX id 0 is UNIX user 'root' [ 0] Trying to map 'root' to Windows user 'root' using implicit mapping [ 1] Using a cached connection to domain.local [ 2] Could not find Windows name 'root' **[ 2] FAILURE: Name mapping for UNIX user 'root' failed with transient errors.

例: 
Error: Get user credentials procedure failed
[  2018] Determined UNIX id 0 is UNIX user 'root'
[  2018] Mapping Successful for Unix-user 'root' to Windows user '<username>' at position 1
[  2750] Hostname found in Name Service Cache
[  2754] Successfully connected to ip <IP>, port 445 using TCP
[  2761] Successfully connected to ip <IP>, port 88 using TCP
[  2770] Successfully authenticated with DC <DC>
[  2793] Could not find Windows name '<AD>\<username>'
[  2793] FAILURE: Name mapping for UNIX user 'root' failed. Explicit Mapping failed and no default mapping found
