[xavier zuniga]

Please someone can help with this:

Developing on Win7;Python2.7;SQLSERVER2008R2.

Already developing on c# against SQLSERVER2008R2 with no problem

Connection string:

db = DAL('mssql://sa:1@DEYANIRA-THINK/aei')

I got this Error:

<type 'exceptions.RuntimeError'> Failure to connect, tried 5 times: Traceback (most recent call last): File "/home/mdipierro/make_web2py/web2py/gluon/dal.py", line 7845, in __init__ File "/home/mdipierro/make_web2py/web2py/gluon/dal.py", line 688, in __call__ File "/home/mdipierro/make_web2py/web2py/gluon/dal.py", line 3454, in __init__ File "/home/mdipierro/make_web2py/web2py/gluon/dal.py", line 669, in reconnect File "/home/mdipierro/make_web2py/web2py/gluon/dal.py", line 3452, in connector Error: ('08001', '[08001] [Microsoft][ODBC SQL Server Driver][Shared Memory]Error de seguridad de SSL (18) (SQLDriverConnect); [01000] [Microsoft][ODBC SQL Server Driver][Shared Memory]ConnectionOpen (SECCreateCredentials()).
