Unable to use domain credentials

[bbgobie]

What happened:
Trying to mount a SMB share with domain credentials.

Issue seems to be with entering the user

tried these formats with the following errors

domain\user

What you expected to happen:
Mount successfully mounted
How to reproduce it:

1. Create SMB share with domain credentials
2. kubectl -n mike-test create secret generic smbcreds --from-literal username='domain\user' --from-literal password='pass' --type="microsoft.com/smb"
3. Standard Nginx sample

Create an SMB share with Domain Credential access

Anything else we need to know?:

Environment:

• Kubernetes version (use kubectl version):
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Others:

Closing as I think the issue might be a network one instead.
So the ticket and the script that adds domain if its in smbcreds.

Tried mounting it manually and was unable to.
