Q: 

TOAD "Credential retrieval failed" error

Semi-regularly when using TOAD, I will try to connect to a DB and get the error "ORA-12638 Credential retrieval failed". I have to restart my TOAD to get past this. It's a pain if I have other connections active. Does anyone know how to avoid or get around this error?

Thanks

+1  A: 

1) Go to /oracle home/network/admin and open sqlnet.ora

2) Search for SQLNET.AUTHENTICATION_SERVICES= (NTS) and change it to SQLNET.AUTHENTICATION_SERVICES= (NONE)

But it arises another problem:after that you will not be able to connect to the database without username/password:>sqlplus / as sysdbaERROR:ORA-01031: insufficient privilegesDo you have any idea?P.S I want to fix "ORA-12638 Credential retrieval failed" and "ORA-01031: insufficient privileges" together not just one of them.
