Hello, I thought it would be better to make a new thread on this specific point though it is related to the other thread I opened yesterday (Trustom not working after upgrade to 3.3.0) So this crash occurs at least in 3.2.6 and 3.3.0 (I raised bug 6034 on 3.2.6 but it also applies to 3.3.0) but not in 3.2.4. I did not check with the intermediate versions, but I guess this must be present since 3.2.6 to current. This crash happens when the remote DC present domain groups with non domain users members (in my case, this was a badly configured trusted samba PDC), and winbindd tries to enumerate the group members. I'd be glad to track this down to the code, but so far I've been unable to build binaries with debug synbols useables by gdb. Fran?ois
