Testing for missing attributes

[<Sim...@wi...>]

Hi,

      I am struggling with composing a filter and I hope someone on the list can
       point me in the right direction.

      I am using Net::LDAP v0.19, perl 5.005_03 against Novell eDirectory

      The script I am working on is to display a list of users who have never
       logged on to the network.

      This is stored in the LDAP attribute lastLoginTime in eDirectory.

      If I make the filter (& (objectclass=inetOrgPerson) (lastLoginTime=*)) I
       get a list of the users who have logged in.

      Can I somehow reverse this so that I get a list of those who do NOT have a
       lastLoginTime attribute ?

      I tried the obvious (& (objectclass=inetOrgPerson) (lastLoginTime!=*)) but
       that just died with a "Bad filter" error.

      It seems that Novell does not return an attribute at all rather than an
       attribute that has a null value.

      My workaround is just to get all the users and then test for the attribute
       in the return list but it isn't going to scale very well ;-)

      All help much appreciated.

      Rgds,
