Storage of User Credentials#

The following provides a summary of where user credentials can be found in LDAP. If you need information regarding Couchbase, please open a support ticket.

U2F devices#

Information about U2F security keys and Super Gluu devices are stored under a fido branch for every user entry. The entries belong to the oxDeviceRegistration object class and contain information about each enrolled device. One way to differentiate between a U2F Security Key and a Super Gluu device is to inspect the oxDeviceData attribute. Super Gluu devices include information there, while U2F Security Keys do not.


We strongly recommend not to modify these attributes directly.

FIDO 2 devices#

Relevant information can be found under fido2_register branch of the user's entry.

TOTP / HOTP devices#

TOTP/HOTP device information is stored in the oxExternalUid attribute as well as in oxOTPDevices.

Phone Numbers#

Verified mobile phone numbers are stored in the mobile attribute of the user entry. Associated information (date added, nickname of device, etc.) is stored in JSON format in the oxMobileDevices attribute.

2FA enforcement policy#

When administrators allow users to set their own strong authentication policy, that is, users being able to decide if 2FA authentication always takes place or only when device/location used is not recognized, the LDAP attributes involved are oxStrongAuthPolicy and oxTrustedDevicesInfo. The former contains the user preference, and the latter the information of his trusted devices and locations.

For privacy reasons, data stored in oxTrustedDevicesInfo is encoded so the only applicable operation upon this data is flushing the list; this can be achieved by removing the attribute entirely.
