Hello Community,
I have got one option to get local sso users and their last login time on vCenter web client under following logs:
/var/log/vmware/sso/websso.log
And
/var/log/vmware/sso/websso-x.log (replace "x" with 1, 2, 3 and so on)
Simply check for particular user details in these logs file:
# cat /var/log/vmware/sso/websso.log | grep username
In the output, just go to the last entry in latest log file. Last entry will start with user's login timestamp.
