Had you activated SAP* user by adapting parameter login/no_automatic_user_sap*? Otherwise the user is disabled.
To activate SAP* emergency user you should fix parameter login/no_automatic_user_sap* to 0 in the profile.
Other option is to reset SAP* user by:
sqlcli -d <Database name> -u sap<sid>,<Password>
<enter>
"delete from usr02 where mandt='<Client>' and bname='SAP*'"
Then you can try user "SAP*" with password "pass".
