Getting ORA-12638 While Installing Secure Enterprise Search 126.96.36.199.0 On Windows Server 2008 R2
Last updated on MARCH 08, 2017
Applies to:Oracle Secure Enterprise Search - Version 188.8.131.52.0 and later
Microsoft Windows x64 (64-bit) - Version: 2008 R2
When installing Oracle SES 184.108.40.206.0 on a Windows Server 2008 R2 machine using the all-in-one install option,
part way through the installation, the error message "ORA-12638 Credential Retrieval Failed" is getting displayed.
Several articles suggest to change the SQLNET.AUTHENTICATION_SERVICES parameter in sqlnet.ora to "(NONE)",
but that does not help further.
