keep getting wrong login error

Hello,

I am ripping my hair out here, trying to connect to

a NW04s SR1 system and despite the fact that I use the correct logon details (checked plenty of times) I keep getting "Name or password is incorrect (repeat logon)" and eventually the user is locked in ABAP.

I see the wrong logon info also in SM21.

I am using the standard example_userlist.php. But saprfc_test.php returns same as well.

Anyone any idea if anything is different with NW04s ?

Thanks & regards,

Andi
