This is a series of patches that depends on patches:

- Improve ipalib.plugins.baseldap classes.

All plugins are converted to extend baseldap classes. This makes things more consistent, fixes some general bugs (with return values for example) and it also makes plugins easier to maintain (as it removes a lot of duplicate code).

Because baseldap classes have features that enable us to define relationships between plugins, I thought it might be best to submit all of the conversions at once and have all the relationships fully defined.

Affected plugins:
config
user
host
service
group
hostgroup
netgroup
rolegroup
taskgroup
pwpolicy

There's also a patch that fixes all unit tests.

Jenny, I included you to Cc, because the patch introduces a lot of changes to the UI (and you're probably not going to like me for this).

Each command extending the LDAP* base classes now has a --raw option. Without it, data from LDAP is formated and translated to human readable. For example:

# ipa user-show admin --all
----------
user-show:
----------
User: admin
  user id: admin
  full name: Administrator
  last name: Administrator
  home directory: /home/admin
  login shell: /bin/bash
  uid number: 999
  gid number: 1001
  gecos: Administrator
  kerberos principal: ad...@pzuna
  last password change: 20090904122852Z
  password expiration: 20091203122852Z
  member of groups: admins

# ipa user-show admin --all --raw
----------
user-show:
----------
  dn: uid=admin,cn=users,cn=accounts,dc=pzuna
  uid: admin
  cn: Administrator
  sn: Administrator
  homedirectory: /home/admin
  loginshell: /bin/bash
  uidnumber: 999
  gidnumber: 1001
  gecos: Administrator
  krbprincipalname: ad...@pzuna
  krblastpwdchange: 20090904122852Z
  krbpasswordexpiration: 20091203122852Z
  memberof: cn=admins,cn=groups,cn=accounts,dc=pzuna
  objectclass: top
  objectclass: person
  objectclass: posixaccount
  objectclass: krbprincipalaux
  objectclass: inetuser

Advantages: more user friendly, allows for easy localization, translation of DNs to primary keys (immediately usable as input to other plugin commands)

I recommend, that you use the --raw flag for testing.



I know it's a lot of changes, so I setup a git repo at:
git://fedorapeople.org/~pzuna/freeipa.git

It should be up-to-date with master and all my patches are applied there. I hope it makes reviewing them at least a bit easier.

Why are you using a pre_callback() to define default values instead of using default_from? It seems clearer to use that.
You're probably referring to the user plugin, where gecos and krbprincipalname defaults are set inside pre_callback. It's a residue from some time ago when we didn't use autofill=True with default_from and it didn't have any effect on optional parameters. It's a small change, but I included an updated version of the patch with this email.

This also duplicates some values in the attribute_names() dictionary. I wonder if this can be either created from the parameters or define a global set somewhere that covers all plugins.
I know, but I couldn't find a better solution. I thought we could add something like a 'real_name' kwarg to params, but this has 2 main disadvantages:
1) it only makes sense with parameters that refer to an LDAP attribute
2) it doesn't work for attributes with no param counterparts

The global set is a good idea as long as we consider only our own plugins. 3rd party plugins would have to modify this set to add their own attributes. Also, attributes might have a different meaning for different objects. They usually don't, but take 'cn' for example. We use it as an ID, name, full name (for users), etc.

In the user plugin 'ou' is in the default attributes. We don't use this attribute.
Since we don't use it, it's not going to get displayed anyway.

All the values in attribute_names, default_attribute and attribute_order are subject to change. I set them to initial values I thought are acceptable, but I don't think I'm the right person to decide what's going to be there. Ideally, someone with more UI/text/user friendliness experience should review it (there's not programming knowledge required to change the values).

I think that in general baseldap needs to be documented to explain how things work. There is no explanation for object_class_config, for example, that it defines the attribute in cn=ipaConfig that contains the default list of objectclasses for the object.
Yeah, there's no documentation at this point, but I'm working on it as we 
"speak".

One more thing, I reviewed your latest patches and they make change to host and service plugins. Your patches should be pushed first, because they are more complex and also more important, so I posted updated versions to the corresponding email threads on freeipa-devel.
