IMC: Backup fails with AAA enabled

[MichaelM55]

Hello,

I just recognized that backup with IMC isn´t working after enabling AAA/RADIUS based login on the switch. It seems I´m missing something.

Let´s look at the switch configuration (HP A5500-EI, Software Version 5.20 Release 2221P20)

• With Putty/SSH I can happily login with user admin@system
• With Putty/SSH I can happily login with user RADIUSuser@mydomain.com
• IMC/SNMP works without any problems:
• 
• IMC+SSH works with user admin@system and RADIUSuser@mydomain.com, e.g.:

• Let´s run "Configuration File Backup Result" within the "Configuration Center":
• 

• What does the switch tell me with "dis log rev":

• Interestingly, backup is running without any problems on other A5500-EI switches where only a normal "admin" user (without any RADIUS, additional domains configuration) is being configured. So it seems I´m missing something?

My guess is that the script isn't handling the extra '@' very well.  What do you see in the imccfgbakdm logfiles?
