If no user name (or auth config) is chosen, we fill up the user name …

[signedav]

But not always. The layer should not be created with it (and have instead no user name). Such functionalities are provided by the PG Kerberos integration.

Backend here https://github.com/opengisch/QgisModelBakerLibrary/pull/114

We need to pass it:

• in ili2db commands (import, validation etc.)
• in generate project (but don't save it in layer sources)
• on direct connections (basket manager, oid manager)

ili2db commands

If no user name available just set the account user name.

generate project

Pass the account user name (the account name) to the library when it needs to connect the db, but not on creating the layers (means only on mgmt_uri)

direct connections
