I have a vCenter version 6.0.0.3 which was turned off for some reason. When I powered it back on, its network settings were deleted! And I couldn't log in with the vCenter root password; it showed an incorrect password error. Using Ubuntu live, I changed the root password, reconfigured the network and DNS settings, and regained access to the vCenter machine.
However, when I tried to log in to the vCenter using the vSphere client, I encountered the incorrect username or password error with both the local administrator@vsphere.local user and the domain users.
I activated SSH and shell on the vCenter (version 6.0.0.3), logged in via SSH, and used the following command to generate a new password for the administrator@vsphere.local user:
/usr/lib/vmware-vmdir/bin/vdcadmintool
But even with this new password, I still got the same error.
Steps I have taken:
- Restarted the vCenter once, but the issue persisted.
- Restarted all services within the vCenter from the shell.
- Manually synchronized the vCenter time exactly with the ESXi host time.
Despite these efforts, the incorrect username or password error persists.
