Hello,
My attempts to create an FSx file system have been failing repeatedly. The connection to our on-prem AD environment is working and the service account is able to create and manage the computer objects in the specified OU. The error it gives me per the troubleshooting document (https://docs.aws.amazon.com/fsx/latest/WindowsGuide/unable-to-create-fs-self-ad.html) is:
"File system creation failed. Amazon FSx is unable to create a file system within the specified
Microsoft Active Directory. To fix this problem, please delete your file system and create a new one
meeting the pre-requisites described in the Amazon FSx user guide."
Which the document above indicates is caused by a unicode character being used at some point in the process. However I have verified none of the input/setting fields contain unicode characters.
