Failed to update user 'user@domain'. Unable to update user.

[Oiligriv]

Hello Community
I'm experiencing strange behavior on the Portal
Below is an extract from the logs

the portal is configured in HA, but the Standby portal always reports this error when users login.
Users complain about login errors from mobile devices.

Error: 

SEVERE
Failed to update user 'christian.carbone@BIM_BL'. Unable to update user.
