Hey **Maxime**, Can you check that the field **oxExternalUid** is present in that user entry in LDAP.

Hello, The attribute is well present : ``` dn: inum=@!3B27.FB71.1131.4C6A!0001!1BCB.BCA8!0000!D735.8499.486E.3E49,ou=people ,o=@!3B27.FB71.1131.4C6A!0001!1BCB.BCA8,o=gluu objectClass: top objectClass: gluuPerson objectClass: gluuCustomPerson mail: m@m.ch oxCreationTimestamp: 20181107094742.063Z givenName: maxime fn mobile: 0041786957005 persistentId: test transientId: maximeTransientId inum: @!3B27.FB71.1131.4C6A!0001!1BCB.BCA8!0000!D735.8499.486E.3E49 iname: *person*maxime oxTrustEmail: {"value":"m@m.ch","display":null,"type":null,"primary":false} oxLastLogonTime: 20181205082320.483Z updatedAt: 20181116120353.190Z oxExternalUid: totp:ey-qrIau5tDA13a0GCDNegRNcTUzJzyHqJMZCrT_Q7eoxbXVBR_A7xqDwU0w xM6If4Dtyd_VLrczTTVadoMkGw== displayName: maxime disn gluuStatus: active sn: maxime ln cn: maxime maxime phoneNumberVerified: true userPassword: {SSHA512}zwcijE0ns1WIap8RfdxGOYvt15WTTnb5XXdayX+KZXr26XxF9k7XCFOJm 2TZlcENSjA3udWtrr5tk3PNPtHo1xLDPXYKBKz6 uid: maxime ```

Maxime, That is a bug in 3.1.4, we already open an issue [here](https://github.com/GluuFederation/oxTrust/issues/1359) to fix that problem

Thank you for your answer.

FYI Gluu 3.1.5 has been released w/ this fix included: https://gluu.org/docs/ce
