Server passing IP instead of FQDN to Kerberos (during SSH GSSAPI)

[Mathew Rowley]

Yes, reverse lookup works correctly...


[root at rsa01 ~]# nslookup 10.252.152.78
Server:         10.252.152.70
Address:        10.252.152.70#53

78.152.252.10.in-addr.arpa      name = kdc01.security.lab.comcast.net.
