System Users

• A system user can login to Versa FlexVNF host OS and CLI. A user is created in Linux when system user is configured.
• Allowed roles: admin / oper
• When assigned admin role, a system user can modify any part of configuration. A system user with oper role can only view the configuration
• Allowed login: shell / cli
• If shell is selected for login, system user will land on bash.When cli is selected, the user will land on CLI prompt.
• System users can SSH to port 22 and port 2024. When port 2024 is supplied to SSH, the user will always land on CLI irrespective of the login configured.
• System user can launch shell from CLI
• Versa FlexVNF also supports password-less authentication for system users using SSH public key.This provides enhanced security and the system is then protected against SSH brute force password attacks. Multiple SSH keys can be configured for a system user

Org Users

• An Org user can only login to Versa FlexVNF CLI

• Allowed login: cli only

• SSH to port 2024 is allowed. Port 22 is prohibited for Org user

• Cannot launch “shell” from the CLI

• Password less authentication is not supported for Org user (as of now)

• Allowed roles: Versa FlexVNF provides various predefined RBAC roles for Org user

• 
  

  adc-admin	Can view/modify ADC specific config only
  cgnat-admin	Can view/modify CGNAT specific config only
  sdwan-admin	Can view/modify config related to SDWAN
  security-admin	Can view/modify Security config only
  tenant-admin	Can view/modify all of tenant config
  oper	Can view all tenant config. No modification allowed

  
  
  

When an Org user is created, we append @Orgname to the username. This is done so that unique Org usernames are created in the system. For instance, in following example, the username would be john@kayak.And user needs to SSH as:

ssh'john@kayak'@77.1.1.1 -p 2024   (or)

ssh77.1.1.1 -l john@kayak -p 2024

root@gotham-cli(config)%set orgs org Customer1 users john role tenant-admin password john123
