Dear All,
Currently i am accessing my file server through server name and are SSO through kerberos. Recently, i have onboarded a GSLB solution which are supposed to failover between my DC and DR. however i get an error when i perform the failover.
upon troubleshooting, i notice that it is due to the kerberos authentication expecting the name of the server when i was access, however the server was another one when i configure it in the GSLB.
server 1: servername1
server 2: servername2
the name that was configured on the GSLB: servername1
so when i access to servername1/folder, in peace time where i am accessing to the DC, no issue with accessing, because the kerberos authentication is expecting servername1.
the issue came when i performed a failover to DR, now when i access to servername1 (the GSLB Name), kerberos authentication fails as it was expecting servername2 now that i have failed over to DR.
i have a question on this, if i am able to workaround this by introducing an additional SPN into servername2, and have it recognized servername1 as an additional server name of the file server access.
