hello,

i have a problem using openldap 2.0 and filters (i'm not sure if its 
openldap specific or not).

i would like to create a user directory with a field storing the date when 
the user was last contacted. (i'm going to use seconds since the begin of 
the epoch because i think that's the easiest solution).

i made a test schema with one integer field for the seconds, but when i try 
to search for values greater or less than a specific value, ldap doesn't 
return anything (no error, but only an empty list).

my filter expression is: (myFoo>=8129)

i tested it with python-ldap and a gnome directory browser called gq.

the python code is:
res = l.search_s(
        "ou=editors, o=sysfrog.org",
        ldap.SCOPE_SUBTREE,
        "(myFoo=8129)",
      )

i have defined the attribute with:
attributetype ( 1.1.2.1.2 NAME 'myFoo'
                DESC 'just a test'
                SYNTAX 1.3.6.1.4.1.1466.115.121.1.27
                SINGLE-VALUE )

does anybody know what's the reason for this behaviour. i'm new to ldap but 
afaik it should be possible to search for "greater than" "less than" 
expressions.

thanks,
