## HoloLens Management Questions
## Questions about managing HoloLens devices
1. **Can I use SCCM to manage the HoloLens?**
1. No. An MDM must be used to manage the HoloLens
1. **Can I use Active Directory to manage HoloLens user accounts?**
1. No, Azure AD must be used to manage user accounts.
1. **Is the HoloLens capable of ADCS auto enrollment?**
1. No
1. **Can the HoloLens participate in WNA/IWA?**
1. No
1. **Does the HoloLens support branding?**
1. No. However, one work around is to create a custom app and enable Kiosk mode. The custom app can have branding which can then launch other apps (such as Remote Assist). Another option is to change all of the users profile pictures in AAD to your company logo. (However, this may not be desirable for all scenarios)
1. **What logging capabilities are available on HL1 and HL2?**
1. Logging is limited to traces captured in developer/troubleshooting scenarios or telemetry sent to Microsoft servers.
### Can I use System Center Configuration Manager (SCCM) to manage HoloLens devices?
No. You have to use an MDM system to manage HoloLens devices.
### Can I use Active Directory Domain Services (AD DS) to manage HoloLens user accounts?
No. You have to use Azure Active Directory (AAD) to manage user accounts for HoloLens devices.
### Is HoloLens capable of Automated Data Capture Systems (ADCS) auto-enrollment?
No.
### Can HoloLens participate in WNA or Integrated Windows Authentication?
No.
### Does HoloLens support branding?
No. However, you can work around this issue by using one of the following approaches:
- Create a custom app, and then [enable Kiosk mode](hololens-kiosk.md). The custom app can have branding, and can launch other apps (such as Remote Assist).
- Change all of the user profile pictures in AAD to your company logo. However, this may not be desirable for all scenarios.
### What logging capabilities do HoloLens (1st gen) and HoloLens 2 offer?
Logging is limited to traces that can be captured in development or troubleshooting scenarios, or telemetry that the devices send to Microsoft servers.

## Troubleshooting Autopilot Device Import
### Clicking Import after selecting CSV does nothing, '400' error appears in network trace with error body **"Cannot convert the literal '[DEVICEHASH]' to the expected type 'Edm.Binary'"**
This error points to the device hash being incorrectly formatted. This could be caused by anything that corrupts the collected hash, but one possibility is that the hash itself, even if completely valid, fails to be decoded.
The device hash is Base64. At the device level, it's encoded as unpadded Base64, but Autopilot expects padded Base64. In most cases, it seems the payload lines up to not require padding, so the process works, but sometimes it doesn't line up cleanly and padding is necessary. This is when you get the error above. Powershell's Base64 decoder also expects padded Base64, so we can use that to validate that the hash is properly padded.
The "A" characters at the end of the hash are effectively empty data - Each character in Base64 is 6 bits, A in Base64 is 6 bits equal to 0. Deleting or adding "A"s at the end doesn't change the actual payload data.
To fix this, we'll need to modify the hash, then test the new value, until powershell succeeds in decoding the hash. The result is mostly illegible, this is fine - we're just looking for it to not throw the error "Invalid length for a Base-64 char array or string".
To test the base64, you can use the following:
```powershell
[System.Text.Encoding]::ascii.getstring( [System.Convert]::FromBase64String("DEVICE HASH"))
```
So, as an example (this is not a device hash, but it's misaligned unpadded Base64 so it's good for testing):
```powershell
[System.Text.Encoding]::ascii.getstring( [System.Convert]::FromBase64String("Q29udG9zbwAAA"))
```
Now for the padding rules. The padding character is "=". The padding character can only be at the end of the hash, and there can only be a maximum of 2 padding characters. Here's the basic logic.
- Does decoding the hash fail?
- Yes: Are the last two characters "="?
- Yes: Replace both "=" with a single "A" character, then try again
- No: Add another "=" character at the end, then try again
- No: That hash is valid
Looping the logic above on the previous example hash, we get the following permutations:
- Q29udG9zbwAAA
- Q29udG9zbwAAA=
- Q29udG9zbwAAA==
- Q29udG9zbwAAAA
- Q29udG9zbwAAAA=
- **Q29udG9zbwAAAA==** (This one has valid padding)
Replace the collected hash with this new padded hash then try to import again.
## Troubleshooting Autopilot OOBE issues
If the expected Autopilot behavior does not occur during the out-of-box experience (OOBE), it is useful to see whether the device received an Autopilot profile and what settings that profile contained. Depending on the Windows 10 release, there are different mechanisms available to do that.
