bug report: samba 2.2.0: MACROS (2) RESOLVED

[Peter Byström]

it seems as if the connections got broken, broken pipe, remote end closed
session etc.
this issue was resolved through changing  security to domain, and setting
password server to the domain controller.

this behaviour is different from the 2.0.x version.

so, the security = share flag seems to be broken in some situations.


best regards,

peter
