I have the system below:
- Windows 7 64Bits
- Visual Studio 2012 with Business Intelligence Template
- Oracle XE 11g Win 32bit
- Oracle SQL Developer 3.2.20
- ODTwithODAC1120320_32bit for .Net
I tried to access Oracle localhost DataBase from SQL Developer and everything is allright.
But, when I try to access the same localhost database from inside Visual Studio 2012 on a Report Server Project, I get the error ORA-12638: Credential retrieval failed.
I have already reinstalled the ODT but without any change.
I have already changed the line below in sqlnet.ora
:
From:
SQLNET.AUTHENTICATION_SERVICES = (NTS)
To:
SQLNET.AUTHENTICATION_SERVICES = (NONE,NTS) OR
SQLNET.AUTHENTICATION_SERVICES = (NONE)
I have already restarted Oracle service without any change.
What can I do ?
This error had happened from one day to another. One day before, it was working, and suddenly it stopped to work.
I do not want to reinstall Oracle, because I can access it from SQL Developer. So, I think it is a VS 2012 problem.
