If the validation of a Credential User fails under the Credentials Tab in WCC, verify that the provided credentials are valid on the WA Agent server.
Release: All Supported Versions
You should see the following message in the $CA_WCC_INSTALL_LOCATION/log/application/config/configui.log
ERROR #VerificationManager # Exception caught trying to login to AutoSys server (hostname): E180011 Login failed using: User=username Password=<hidden>
On your WA Agent server:
1) Navigate to /opt/CA/WorkloadAutomationAE/SystemAgent/WA_AGENT directory
2) Run ./password <cred user password>
3) Run ./chkusr <cred username> <encrypted password>
Should return "User and Password okay"
If this is not the case, then the problem could be that username doesn’t exist on AE and/or password is invalid.
