I have tried without a successful result the change of the first password of the Web Servers System Experience and Service portal through the console vmware
Password as <8FC-rtE>phm&bB Al#g0t@W1f5.rup P+46H!C#MPjr8y5+ Are not accepted.
I have tried different versions of web suite and the result is the same
local host login: polycom
(current) UNIX password: polycom
New Password: Al#g0t@W1f5.rup
Repeat New Password: Al#g0t@W1f5.rup
It is okay.
