Error authenticating with mongo 3.0

[rchamorro]

When using mongodb_backend with authentication we have this error when updating a module (giscedata_telegestion_comer):

Traceback (most recent call last):
File "./openerp-server.py", line 112, in <module>
tools.config['update'])
File "/home/erp/src/erp/server/bin/pooler.py", line 42, in get_db_and_pool
addons.load_modules(db, force_demo, status, update_module)
File "/home/erp/src/erp/server/bin/addons/init.py", line 786, in load_modules
r = load_module_graph(cr, graph, status, report=report)
File "/home/erp/src/erp/server/bin/addons/init.py", line 630, in load_module_graph

result = obj._auto_init(cr, {'module': module_name})
File "/home/erp/src/erp/server/bin/addons/mongodb_backend/orm_mongodb.py", line 52, in _auto_init
db = mdbpool.get_db()
File "/home/erp/src/erp/server/bin/addons/mongodb_backend/mongodb2.py", line 225, in get_db
raise except_orm('MongoDB connection error', e)
osv.orm.except_orm: error -- MongoDB connection error
error -- MongoDB connection error

We were able to solve it changing the uri property of mongodb2.py to not include the database name. Like this:

Line 137:

uri_tmpl = 'mongodb://%s:%s@%s:%s/?authMechanism=%s'
uri = uri_tmpl % (tools.config['mongodb_user'],
                                  tools.config['mongodb_pass'],
                                  tools.config['mongodb_host'],
                                  tools.config['mongodb_port'],                                  
                                  tools.config['mongodb_auth'])

But it then it fails authenticating with normal usage of the module :(

@rchamorro The URI build should resemble to Official Mongodb Uri documentation:
mongodb://[username:password@]host1[:port1][,host2[:port2],...[,hostN[:portN]]][/[database][?options]]

I think this is related to the "?options" concatenation to the URI.
The "database" section is mandatory on some methods for the MongoDB Pool Class.

I think this should be fixed as we work with Mongo 3.0.12 @jaumef can you confirm it works?
