[Samba] sambaNTPassword does NOT write to master LDAP when machines auto change the values
We have SuSE SLES9 servers with LDAP master/slave replication (24 replications/BDC's) All working fine -joining domain etc. The problem I am having is PC's at remote sites (BDC) with a local replica (OpenLDAP) periodically change the sambaNTPassword/sambaLMPassword on there own and write to the local LDAP server and do NOT follow the referral to the master. I have written scripts to force the sambaNTPassword attribute to be re-synchronised but the attribute becomes a different value - at a variable timeframe. Further investigation suggests that NT/W2K/W2K3/XP have different times when they auto change the sambaNTPassword vaue - (avoid replay attacks??). However 3.0.14a that is distributed/updated on SLES9 only writes this info to the local BDC and not the centre/MASTER. 7 days for NT 4, 30 days for W2K/XP is the default policy for the machines to auto change the sambaNTPassword/sambaLMPassword. I have also noticed that using pdbedit to change a value will change the local OpenLDAP server and not follow the referral to the master. So that changes at the BDC's are out of sync with respect to the master. Joining the domain works great and replicates ALL attributes correctly (inc sambaNTPassword) FYI - This is the fix by local admins to allow machines to connect to the domain again. Can you help on this subject - this is causing major issues with machines moving sites!!! Best Regards Paul Hanson try { document.title document.getElementById("subject").innerHTML; } catch (e) { }
