Account Management should not eat backslashes in domain\account

Current Situtation

• When adding a user account to JOC Cockpit by use of the Account Management view then user accounts can be written like this: domain\account (alternatively to account@domain)
• JOC Cockpit writes the correct domain\account to the shiro.ini(.active) file. However, in the GUI the backslash is dropped, typically after switching views and returning to the Account Management view then the account is displayed as: domainaccount, i.e. the backslash is missing.

Desired Behavior

• Backslashes in user accounts should be preserved.
