When connecting to SQL server via keytab warning shown as SPN not available in the keytab file

问题

I have some doubts regarding generating a keytab file for SQL server kerberos authentication.

SQL server's SPN is:

MSSQLSvc/myhost:1433@MYDOMAIN.COM 

I have created keytab file as:

ktpass -out "C:\Users\myuser\KerberosConf\MSSQL\myappserver.keytab" -princ MSSQLSvc/myhost:1433@MYDOMAIN.COM -mapUser mydomain\myuser-pass Test@123 -crypto AES256-SHA1 -pType KRB5_NT_PRINCIPAL 

When viewing the keytab it shows the correct SPN as:

[1] Service principal: MSSQLSvc/myhost:1433@MYDOMAIN.COM KVNO: 18 

But while referring the keytab file for authenticating it throws the below error:

Debug is true storeKey true useTicketCache false useKeyTab true doNotPrompt true ticketCache is null isInitiator true KeyTab is C:/Users/myuser/KerberosConf/MSSQL/myappserver.keytab refreshKrb5Config is false principal is MSSQLSvc/myhost:1433@MYDOMAIN.COM tryFirstPass is false useFirstPass is false storePass is false clearPass is false Key for the principal MSSQLSvc/myhost:1433@MYDOMAIN.COM not available in C:/Users/myuser/KerberosConf/MSSQL/myappserver.keytab 

[Krb5LoginModule] authentication failed Unable to obtain password from user

Please kindly help me to resolve this
