* How to import LDAP users in `CubicWeb`?

  Here is a very useful script which enables you to import LDAP users

  into your `CubicWeb` application by running the following: ::

    import os

    import pwd

    import sys

    from logilab.common.db import get_connection

    def getlogin():

        """avoid usinng os.getlogin() because of strange tty / stdin problems

        (man 3 getlogin)

        Another solution would be to use $LOGNAME, $USER or $USERNAME

        """

        return pwd.getpwuid(os.getuid())[0]

    try:

        database = sys.argv[1]

    except IndexError:

        print 'USAGE: python ldap2system.py <database>'

        sys.exit(1)

    if raw_input('update %s db ? [y/n]: ' % database).strip().lower().startswith('y'):

        cnx = get_connection(user=getlogin(), database=database)

        cursor = cnx.cursor()

        insert = ('INSERT INTO euser (creation_date, eid, modification_date, login, firstname, surname, last_login_time, upassword) '

                  "VALUES (%(mtime)s, %(eid)s, %(mtime)s, %(login)s, %(firstname)s, %(surname)s, %(mtime)s, './fqEz5LeZnT6');")

        update = "UPDATE entities SET source='system' WHERE eid=%(eid)s;"

        cursor.execute("SELECT eid,type,source,extid,mtime FROM entities WHERE source!='system'")

        for eid, type, source, extid, mtime in cursor.fetchall():

            if type != 'CWUser':

                print "don't know what to do with entity type", type

                continue

            if source != 'ldapuser':

                print "don't know what to do with source type", source

                continue

            ldapinfos = dict(x.strip().split('=') for x in extid.split(','))

            login = ldapinfos['uid']

            firstname = ldapinfos['uid'][0].upper()

            surname = ldapinfos['uid'][1:].capitalize()

            if login != 'jcuissinat':

                args = dict(eid=eid, type=type, source=source, login=login,

                            firstname=firstname, surname=surname, mtime=mtime)

                print args

                cursor.execute(insert, args)

                cursor.execute(update, args)

        cnx.commit()

        cnx.close()
