KB-1920: Configuration parameters dns.dc.<>: and dns.gc.<>: are case sensitive

When you configure dns.dc.<>:<hostname>[hostname] and dns.gc.<>:<hostname>[hostname] in centrifydc.conf in upper case it will cause a DNS is down warning:

Aug 25 12:46:47 abcd adclient[6398]: INFO <main> dns.state DNS is down
Aug 25 12:46:47 abcd sshd[6402]: Connection from port 4713
Aug 25 12:46:53 abcd adclient[6398]: INFO <fd:18 get object> base.bind.healing
Lost connection to . Running in disconnected mode


dns.dc/dns.gc parameters are used to override / bypass DNS lookup of SRV records for the domain. The domain name must be specified in lower case, otherwise it does not work.


Please enter domain names in all lower case, for example: nosuchhost nosuchhost

NOTE: You can also add a dot "." at the end of the line to improve performance: nosuchhost. nosuchhost.
