commit 1d9542df5d2ae5c21a1e96d100f899b3d7b2f27c
Author: Jan Kara <jack@suse.cz>

    Don't link all binaries with ldap library
    
    The default action-if-found of AC_CHECK_LIB() is to append checked
    library to LIBS. Thus check for ldap library resulted in unwanted
    addition of -lldap to LIBS as [] is an empty string in M4 and the
    default action is used.
    
    Fix the problem by providing proper action-if-found which was currently
    just hidden behind the check. Also do similar cleanup for
    AC_CHECK_HEADER check although there it didn't have any undesired
    side-effect.
