While accessing the Symantec Endpoint Protection Manager (SEPM) Web Console, if the tab key is pressed to enter the password after typing the "User name", only the first character of the password gets typed.
Direct URL Format for SEPM 14.3.x: https://SEPM_IP:8443/console/apps/sepm
SEPM 14.3.x
Known Issue
This issue is fixed in SEPM version 14.4.
The port number in direct URL is also changed from 8443 to 8446: https://SEPM_IP:8446/console/apps/sepm
As a workaround in SEPM 14.3.x, the cursor/mouse needs to be clicked to type the complete password.
