spn

Hi everyon,

I am not a Maximo Person.

My organization uses Maximo 7.5.0.3. they use SSO as well as authentiation from their Maximo.
I have a windows Domain, the forest and domain functional level is windows2003 if i change the domain and forest functional level to windows 2008 will it effect their application.

i remember i have used the below command to generate a key for them(SPN).
ktpass -out appsrv.keytab -princ HTTP/maximoserver@mydomain.com -mapuser maximouser -passP@ssw0rd -ptype KRB5_NT_PRINCIPAL

does changing forest & domain functional level on my domain controller will effect their application ?
