Impersonation plugin

This plugin allows certain users to assume the identity of another user. A privileged user first logs in with its real account and can then choose another profile to appear as. This feature can be especially useful for training/learning or development platforms.

This plugin should not be used on production instance, prefer ContextSwitching plugin.

Configuration

Just enable it in the Manager (section “plugins”) by setting a rule. Impersonation can be allowed or denied for specific users. Furthermore, specific identities like administrators or anonymous users can be protected from being impersonated.

You HAVE TO modify REMOTE_USER to log both real AND spoofed uid.

Set a macro like this :

_whatToTrace -> $real__user ? "$real__user/$_user" : "$_user/$_user"

and set Genaral Parameters > Logs > REMOTE_USER with _whatToTrace

Both spoofed and real session attributes can be used to set access rules, groups or macros.

By example : $real_uid eq 'dwho' or $real_groups =~ /\bsu\b/

Keep in mind that real session is computed first. Afterward, if access is granted, impersonated session is computed with real and spoofed session attributes if Impersonation is allowed.

By example, to prevent impersonation as 'dwho' set Identities use rule like :

$uid ne 'dwho'

impersonationPrefix is used to rename user's real profile attributes. You can set real attributes prefix ('real_' by default) by editing lemonldap-ng.ini in section [portal]: 

[portal]
impersonationPrefix = real_
