While we are login to UCCX administration page, some time we get an error


Security exceptions throw authenticating User uccxadmin. Authentication failed: Cannot authenticateuser: uccxadmin Please use the browsers back button to go back to the login page.”

Most of the cases this might be with a wrong password we entered, so as a first step we can go to the CUCM end user page and edit the “UCCX admin” user with a new password then try to login again.

If we are getting the same error again then there might be an issue with the LDAP authentication, more specifically it’s between uccx and cucm authentication.

On this case we can apply “CET” (Note this is a TAC recovery tool and will not advice to do the same in production, without Cisco TAC presence or advice. But in Lab scenario off course we can)

  • Run “C:\Program Files\wfavvid\cet.bat”
  • At the warning message click “No”
  • In the list of Configuration Object Types, select “com.cisco.crs.cluster.config.AppAdminSetupConfig”
  • In the right pane, select the one record that appears, right click and select “Modify”
  • In the dialog window that appears, select tab “com.cisco.crs.cluster.config.AppAdminSetupConfig”
  • The field “Setup State” is set to “DONE”. Change it to “FRESH_INSTALL”. Click “OK” / “Apply”
  • Star>run: – services
  • Restart service “Cisco Unified CCX Node Manager”
  • Open a new appadmin page and login with the initial credentials (Administrator – ciscocisco)
  • You are now in the initial setup wizard again. Navigate through the pages. Your previous configuration should still be in place.
  • When you are asked for the licenses enter the same license file again.
  • In the last page you can select admin users again. Select new admin users from the list of CM End users.
  • Finish the wizard.
  • You can now login again with the new admin user! All other configuration has been preserved.


Tips for CCIE:-

End-user should assign in to “supper user group” and the group should contain “Standard AXL API Access” role. May be lab proctor change the group or role from end-user which lead to login problems.

    Cisco documents doesn’t say restart of CCX node service, and it didn’t work until you restart it. I found about it on your site, Thank you so much for the help
