Ok, the problem is the following: (I would get the same trouble on my 
production systems if I upgrade them, but they're running Sarge)

upgrade procedure:
  - stop slapd
  - check if user exists (including group) getent
  - adduser if it doesn't exist
  - standard procedure to upgrade a database.

At the moment it checks for the user the LDAP database is down (I assume 
that libnss-ldap is using the database at localhost) which causes getent 
group openldap to hang.

Solution:
Move the checking code to the preinst before stopping slapd, add a flag 
to /var/lib/slapd that the user exist or not. And create the user 
according to that in the postinst. (Or add the user in the preinst too)

Until someone comes up with a better solution, I'll implement that 
tonight and hopefully my sponsor is available to upload.
