In today’s article, we will talk about ORA 12638 credential retrieval failed tips.

For the solution, we need to make the following change in sqlnet.ora

Instead of

SQLNET.AUTHENTICATION_SERVICES= (NTS)

1	SQLNET.AUTHENTICATION_SERVICES= (NTS)

This is written

SQLNET.AUTHENTICATION_SERVICES= (NONE)

1	SQLNET.AUTHENTICATION_SERVICES= (NONE)

This error will be fixed.

$ vi sqlnet.ora
SQLNET.AUTHENTICATION_SERVICES= (NONE)

1 2	$ vi sqlnet.ora SQLNET.AUTHENTICATION_SERVICES= (NONE)
