[Building Sakai] JLDAPDirectoryProvider -- LDAPException: ServerMessage: NDS error: insufficient buffer (-649)

[Stephen Marquard]

At a guess I would say it's an issue with your LDAP server.

Try an ldapsearch from the command line to verify whether it's doing what you expect it to be doing.

We've got a sudden mystery: Sakai 2.6 (v62856), has been working just
fine until this morning... now we're getting insufficient buffer from
LDAP?

LDAP server hasn't changed overnight, sakai.properties hasn't changed
overnight...

Any ideas or suggestions as to what would be happening here are welcome.
