folks;
I'm going to use LDAP on Solaris 10 to authenticate users, i have 3 questions, i'm hoping it can be possible:

1. when users login for the first time, Is there a way to auto create a home directory like "/home/"user_name" so we don't have to a create a home directory for every single users (we will have about 300 users that going to need access to that Solaris box.

2. If question 1 can be done, is there a way to assign group to each user as well?

3. If question 2 can be done, Is there a way to make the group assignment based on their own group in LDAP?
In other word, let's say i have 2 groups in LDAP called "new & old", then if a user from group "old" in ldap logs in to the Solaris box he should be assigned to group "staff" and if a user from group "new" in ldap logs in, the associated group on Solaris box would be "sysadm"

Help is very appreciated
