Description

When setting the returning attributes of a search to the space character the server returns a protocol error:

ldapsearch -H ldap://localhost:10389 -x -D "uid=admin,ou=system" -W -b "ou=users,ou=system" -s base -a always "(objectClass=*)" " "

The result is the following error:

   result: 2 Protocol error
