Changing Run As User in TSMUI with a Netbios Name that Includes a Period Fails With Error

Issue

Changing run as user in TSMUI with a netbios name that includes a period fails with this error message:

"The username must be specified as 'domain\user' with the domain being in the short (NetBIOS) format"

Environment

Tableau Server 2018.2.0
Windows Server 2016

Resolution

This behavior is caused by a known issue, ID 820229, which is currently under investigation by the Tableau Development team.

See Known Issues, 820229.

Cause

The netbios name contains a ". " and our check for netbios names format assumes that it is not a netbios name.

wgserver.domain.fqdn: domain.com
wgserver.domain.nickname: DOMAIN.COM
wgserver.domain.default: local.domain.com
