Cause

Issue is caused when specifying the management username with a domain name after it.

Example:

Using username "management@vsphere.local" will cause deployment to fail at step 27

However,

Using username "management" will successfully create the management account.

Resolution

To resolve this issue:
If you're mid deployment you'll need to update the config-journal.json ( & possibly the config-initial.json) file with the correct user name for the PSC/VCSA management user only, by dropping the domain portion (ie. @vsphere.local). Once you update the file restart marvin service and re-try validation. You shouldn't have to RASR the nodes and start the build again. 
*This might also happen during node adds.

You may also RASR nodes and retry the deployment and use management username without a domain.  (If the above step fails and you still get the same build error)

Example: "management"

Another issue might come up in 4.7.535 is that the password provided in the wizard is accepted, but isn't supported. Use of ! is not allowed. Special char - is allowed, so used that:

Steps to fix this:

1) Generate the new blowfish with the new password:

echo -n "T3st-01" | openssl bf-cbc -iv 62726f6f6b697673 -nosalt -K $(xxd -p < /etc/vmware-marvin/password.key) | xxd -p

2) The return of this command will be needed to edit the /var/lib/vmware-marvin/config-journal.json file. Search for the entry vcManagementAccount and change the blowfish to the above generated.

3) Restart service vmware-marvin  and try again.
