Dell EMC Unity: Adding SPN fails with error Execution failed : valid_passwd : Precondition violated. (User Correctable)

Adding SPNs to a NAS Server.
 

Adding SPNs to NAS Server from Unity CLI throws following error:
Execution failed : valid_passwd : Precondition violated.

Password of Domain user which is used to add SPNs contains one or more special characters that the Unity CLI does not accept.

There is a set of special characters which are not accepted by Unity CLI directly.
These are special characters that have predefined meanings in Linux.

Some of them are:    &     (      )     -     ;      ?

You can use the password by Quoting i.e; using the password in single quotes.
Or change the password so that none of these special characters are in the password.


Here's an example of the command failing when the password of domain user was abcd&^12*

Unity Name spa:~> svc_cifssupport testnas -setspn -add host/testalias.ourteam.com@OURTEAM.COM -compname testnas -domain ourteam.com -admin Ukasha
Enter Password for Ukasha:
sh: Password^12*: command not found

Error 2237: testnas : Execution failed : valid_passwd : Precondition violated. 

If the password is entered as 'abcd&^12*', the command runs successfully.
