Description
Describe the bug When exposing custom attributes via the LDAP outpost, nested attributes are not returned as individual LDAP attributes. Instead, they appear in a serialized map format that does not seem to comply with LDAP.
To Reproduce Steps to reproduce the behavior:
- Configure a user in Authentik with a custom attribute containing nested values, e.g. settings.locale = en.
- Query the user via the LDAP outpost using ldapsearch.
- Inspect the LDAP response.
See that the attribute is returned as a serialized map string rather than as a proper multi-valued LDAP attribute.
Expected behavior I would expect the LDAP outpost to flatten or map the nested attribute into standard LDAP attributes, for example:
settingsLocale: en
or
settings.locale: en
instead of:
settings: map[locale:en]
Version and Deployment (please complete the following information):
- authentik version: 2025.8.3
- Deployment: Docker
