I have successfully setup Kerberos authentication between Oracle RAC Database 11.2.0.4 running on Linux Server, Windows 10 on which oracle client 11.2.x.x is running.



Issue -
(1) There is an intermediate connection failure with error - ORA-12631: Username retrieval failed



Error frequency is very uncertain - Sometimes it comes after 20 successful attempts of connection (sqlplus /@connect_string) or sometimes after 5 successful attempts.
Configuration looks good. I have used most of the default parameters except specific to required for the AD.
Database server is not in AD domain.



(2) I am not able to generate any logging mentioned in krb5.conf file - neither on server side nor client side
more /etc/krb5.conf
[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log



Appreciate your response in advance.



Thanks.



Regards,
Gaurav
