[Samba] Network mapping to a windows domain

[Rafael Paris]

Hello everyone.

We have two domain in our company, a windows pdc and a samba pdc.
Samba users have access to windows' shared resources at login script using
ntlogon.py passing the windows domain username and password as parameter.
Clients connect with no problem but after a period of time we loose the
connection to the windows domain.
Can anyone address me in the correct direction to fix this problem?

Thanks in advanced,

Rafael Paris
