Chapter 22 Kerio Clientless SSL-VPN

counts authenticated only in WinRoute (Internal user database authentication) cannot be used to access SSL-VPN . For details on local user accounts, refer to chapter 13.2.

•If it is a mapped Active Directory domain which is set as primary (or if only one domain is mapped), it is possible to specify username either leaving out the domain (jdolittle) or with the domain (jdolittle@company.com).

• If it	is a mapped Active Directory domain		which is	not set as pri-
mary,	the domain must be included in	the	username	speciﬁcation (e.g.
sidneywashington@usoffice.company.com).
