Hi, I am using Samba 3.5.4 under Debian Linux and Windows 2003 Server as ADS/DC controller with domain compatibility level is set to Windows 2000. We have over 100 ADS/DC controllers in the same domain forest and while I try to connect to one of them connection is established successfully but after some random interval Samba lose connection with ADS/DC server and users accounts from domain are inaccessible. If I reestablish the connection it work properly for some time. Also I noticed that when I'm connected to ADS/DC, after some time IP from LDAP server changes - it is taken from another DC controller in domain forest. Is there any solution to prevent Samba from changing IP of LDAP server after connection to ADS server is successfully established ? Does Samba work in multi ADS/DC environment ? Thanks in advice. net ads info LDAP server: 172.29.30.12 # this IP changes after some time LDAP server name: dc101.domain.local Realm: DOMAIN.LOCAL Bind Path: dc=DOMAIN,dc=LOCAL LDAP port: 389 Server time: xxx, xx xxx xxxx xx:xx:xx CET KDC server: 172.29.30.12 Server time offset: 10
