System.DirectoryServices.AccountManagement is not supported on this platform

Octopus Server

Hi,

we are testing a dry run migration from our Windows on-premise to Docker container.

What we did so far:
1 - we set up a new docker Octopus instance with the same version as our on-premise Octopus instance has
2 - we backup the on-premise SQL database
3 - we restored the on-premise database into a different SQL server and pointed docker Octopus into that DB ( plus we created an SQL user and give him access to the SQL server - so new Docker Octopus can fully use DB)

And now the fun part begins - The old Windows instance uses NTLM authentication, thus our Docker instance fails with the error:

System.DirectoryServices.AccountManagement is not supported on this platform.
System.PlatformNotSupportedException

Terminating process with exit code 100
Full error details are available in the log files at:

If you need help, please send these log files to Help & Support - Octopus Deploy

And my question is:
Is there a possibility to switch NTLM off somewhere in the Database so the Docker instance will use only username&password authentication?

And you can close that ticket!

The problem was fixed by restarting POD and inserting a command before POD went into the crash loop:

/Octopus.Server database --connectionString "$DB_CONNECTION_STRING" && ./Octopus.Server configure --activeDirectoryIsEnabled=false
