Getting ORA-12638 While Installing Secure Enterprise Search On Windows Server 2008 R2 (Doc ID 1580091.1)

Last updated on MAY 03, 2023

Applies to:

Oracle Secure Enterprise Search - Version and later
Microsoft Windows x64 (64-bit) - Version: 2008 R2


When installing Oracle SES 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 changing the SQLNET.AUTHENTICATION_SERVICES parameter in sqlnet.ora to "(NONE)", but that does not help further.
