# ldif
Utilities for working with ldif data. This implements most of RFC 2849.
## Change Entries
Support for moddn / modrdn changes is missing (in Unmarshal and
Marshal) - github.com/go-ldap/ldap/v3 does not support it currently
## Controls
Only simple controls without control value are supported, currently
just
Manage DSA IT - oid: 2.16.840.1.113730.3.4.2
## URLs
URL schemes in an LDIF like
jpegPhoto;binary:< file:///usr/share/photos/someone.jpg
are only supported for the "file" scheme like in the example above
