Using <= with * in the assertion value looks bogus to me.

Does not work for me when using OpenLDAP's ldapsearch:

$ ldapsearch "(|(last-login-time<=100101*)(\!(last-login-time=*)))"
ldapsearch: ldap_search_ext: Bad search filter (-7)

Note the extra back-shlash needed before ! since ! is a special char
for the shell.

You should not pass complete filter strings to
ldap.filter.escape_filter_chars(). This function should only be used for the
assertion values you put into the filter string afterwards.
