Depenging on how username is provided in login page, session.logon.last.domain variable might not be setted.

session.logon.last.domain is used be default on NTLM sso config.

As you have AD Auth on the VPE, I would suggest changing the sso configuration to use session.ad.last.actualdomain as the domain source and try again.
