ORA-28040: No matching authentication protocol in version 11.2.0.3

789546Feb 16 2012 — edited Feb 16 2012

Hi,

I am working on database server 11.2.0.3 and the OS is linux 86 bit. i created an entry in sqlnet.ora file with

SQLNET.ALLOWED_LOGON_VERSION = 10

it is failing with ORA-28040: No matching authentication protocol error and i am not able to connect as sys till I comment the entry. How do i set this entry and where in the client side do I need to set this entry? Also, do I have to set it to SQLNET.ALLOWED_LOGON_VERSION = 11 instead? I am confused. Please help

thanks a lot.
