Have you checked your Directory Service connector? It sounds like something you inputed that uses your credentials needs to have it's password updated, and my guess would be the Directory Service connector.
I agree with wolram, it's probably the Active Directory connector, though you may have other tools (Cisco IDS or the like) that you setup with RADIUS or TACACS credentials linked to the domain. Ideally, the LEM would have a service account for domain queries.
You can get to the AD connector by going to Manage --> Appliance, clicking the gear to the left of the LEM and clicking "Connectors." Look for "Directory Service Query," stop and edit the tool to change credentials.
Thanks for your reply.
It does help. Just wondering if Ideally, the LEM need a service account
for domain queries.
Could you pls specify what is the "service account" ?
Is it a domain account created in Active Directory?
What special permission does this account need?
Does it need domain administrator's permission ?

A service account is an account created in Active Directory, usually with the option to have a password never expire, which is used for automated jobs or applications to use to take advantage of Active Directory.
For the LEM's AD connector, no special permissions are required, and it doesn't need to be a domain admin. The account is used just for directory queries.
