Kerberos Authentication on Client errors Oracle db12.2-how properly configure or bug???

edited Nov 20, 2020 7:31PM in Database Security Products (MOSC) 2 commentsAnswered

When I try to authenticate with Kerberos running sqlplus on Windows I am getting ORA-01017 Invalid username/password Oracle 12.2 when specify SQLNET.AUTHENTICATION_SERVICES= (beq,kerberos5pre)

when I do the same with SQLNET.AUTHENTICATION_SERVICES= (beq,kerberos5) I am getting ORA-12641 (see below) :
