Distcp between secure clusters in different Kerberos realms
To use distcp between two secure clusters in different Kerberos
realms, you must use a single Kerberos principal that can authenticate to both realms. In
other words, a Kerberos realm trust relationship must exist between the source and
destination realms. This can be a one-way trust (in either direction), a bi-directional
trust, or even multiple one-way trusts where both the source and destination realms trust a
third realm (such as an Active Directory domain).
