I reinstalled my Solution Manager 7.1 and upgraded to SP12. My landscape was connected to it via diagnostic agents without any problems. Now at the Solman setup Basic settings none of my systems are connecting to it. I can see every system but on 6.7 connect diagnostic agent page all of them, including Solman's DA is giving me Logon Denied error.
On agent management page, I did push credentials to every system but it didn't work.
I tried smdsetup.bat sldconf hostname:"FQDN" port:"50000" user:"SLDDSUSER" pwd:"user password" and smdsetup.bat managingconf hostname:"FQDN" port:"50004" user:"SMD_AGT" pwd:"user password".
Both users have necessary standard roles plus SAP_ALL and SAP_J2EE_ADMIN roles.
What else can I do? As last resort I am thinking reinstalling all agents but it will take too much time.
