We have devices which use ACS as AAA. On most of the devices, there is a need to put the login/password multiple times( around 2 to 3) before it successfully allows to login.
If the logins are again followed up within a very short duration it sometimes allows you within first attempt, but as a whole it needs atleast 2 attempts before ACS allows us in even with correct logins.
Any suggestions to rectify this would be appreciated.
Thanks.

Check the logs in ACS (failed authentications) and check the log in the router. If it's losing communications with the ACS server, it will be in there and pretty obvious.

ACS gives me following error:
External DB user invalid or bad password; for the first two attempts & the third attempt is successful. There are no link issues between this device/ACS.
Thanks.

Where are the user accounts? Are they local on ACS or is ACS proxying to something like Windows AD?

the users accounts are linked to windows AD database.

That typically means 1)you entered the wrong password 2) communication problems between ACS and the domain controller(s)

Hi thomas,
I am also experiencing the exact same issue.We have 2 ACS appliance and whenever i try to do VPN connection , at first attempt it is prompting 2 times to enter AD user name & password.Once it get connected and when i try to reconnect, it will ask for 1 time only.
It would be highly appreciated if you could provide me the solution for this issue.
