The Domain based service account password for the Sharepoint server was changed, however user access was still working.
Solution
Sharepoint will continue to operate under the previous conditions until the server is rebooted and an IIS reset is initiated. Basically, when the Sharepoint services are restarted. Sharepoint provides a power shell script to reset the password.
For Example:set-SPManagedAccount ›UseExistingPassword -Identity PLM\<serviceaccountuser>
MUST RUN USING "RUN AS ADMINISTRATOR"
---- ERROR RETURNED WHEN RUNNING THE ABOVE SCRIPT -----set-SPManagedAccount : Error deploying administration application pool credentials. Another deployment may be active. An object of the type Microsoft.SharePoint.Administration.SPAdminAppPoolCredentialDeploymentJobDefinition named "job-admin-apppool-change" already exists under the parent Microsoft.SharePoint.Administration.SPTimerService named "SPTimerV4". Rename your object or delete the existing object.At line:1 char:21+ set-SPManagedAccount <<<< -UseExistingPassword -Identity PLM\yyhsvclient40 + CategoryInfo : InvalidData: (Microsoft.Share...tManagedAccount: SPCmdletSetManagedAccount) [Set-SPManagedAccount], InvalidOperationException + FullyQualifiedErrorId : Microsoft.SharePoint.PowerShell.SPCmdletSetManagedAccount

1. WHEN THIS PROBLEM IS SEEN YOU NEED TO GO TO IIS AND RESET THE L O G I N / P A S S W O R D FOR CENTRAL ADMINISTRATION APP POOL.
2. RESTART THE CENTRAL ADMIN APP POOL
3. OPEN CENTRAL ADMIN
4. GO TO MONITORING/TIMER JOBS/REVIEW JOB DEFINITIONS
5. LOOK FOR THIS RUNNING JOB "ADMINISTRATION APPLICATION POOL CREDENTIAL DEPLOYMENT"
6. DELETE THIS JOB
