APAR status

  • Closed as program error.

Error description

  • The TLS support ( for encryption/authentication) built into the
new communication layer used by AD Build Client and AD Connect
does not currently support the use of TLS certificates that set
the common name (CN) to a host name/domain name (eg. ibm.com ).
It only supports IP addresses, like (eg 127.0.0.1).

This restriction will not allow customers to enable TLS on
their systems, since the use of host name / domain name in the
CN or subject alternate names (SAN) field of certificates is a
standard and recommended best security practice.

Local fix
