It can't import all groups

Hi you all. I've tried to find information about that on other support and bug threads and I'm afraid I haven't found a solutions. I've installed very succesfully the LDAP integration module using 5.x-1.3.

The problem is that it doesn't import all the groups we have created for the set of users we allow to login to our drupal. I think that the reason is that the field "ldap_group_entries" which the module "ldapgroups" add to the table "ldapauth" is defined as "varchar(255)". That's the reason that it truncated the list of groups we have defined on our LDAP environment and we expect to import as roles on drupal. This field is to short and it's only allowing us to import the first 5 groups out of just 8 (we're not trying to import hundreds of groups as an stress test ;-).

I've set the priority as critical since my impression is that the problem is not difficult to solve and it makes the ldapgroups.module useless, unless you only have grouped your user list on just a few groups.

Any idea?
