vim-ldapschema
VIM LDAP schema syntax files + autocommands; you know the drill.
Note: Looking for the author
I'm not the author. I have no idea where I found these files, I can't remember the source and google does not find any of the keywords I searched for. The vim script archive does not have it either.
If you're the author, let me know at miroslaw+p+misc at makabra.org.
