Hi all I have been using samba 3.0.21 with openldap , and facing some problems. since i am using samba with openldap, samba hangs abruptly, I have tuned openldap with DB_CONFIG parameters my DB_CONFIG file is as follows ######################################### set_cachesize 0 150000000 1 set_lg_regionmax 262144 set_lg_bsize 2097152 #set_lg_dir /var/log/bdb set_flags DB_LOG_AUTOREMOVE ######################################### but after i do db_recover and start my ldap and samba, i have to rejoin all my clients system to PDC, though the entries in LDAP of all my computers exist, why does this happens. After Rejoining, i often get the following messages in /var/log/messages in my PDC server 1.creds_server_check:- credential check failed 2. smbd api_samr_set_userinfo: Unable to marshall SAMR_Q_SET_USERINFO 3. net_sam_logon: creds_server_setup failed. Rejecting Auth Request from cleint TEST1$ machine I have file server having redhat linux 4 and samba 3.0.10 , which is joined to PDC, The smb.conf i have given security=domain, and workgroup i hav mentioned the domain name . i have given the following command to join the fileserver to my PDC, system#net rpc join -U root%not24get Joined to MYDOMAIN.COM the above message says, that it has joined to domian, but when i give command system#net rpc info i get the following message rpc_parse/parse_prs.c prs_mem_get(537) prs_mem_get: reading data size 14418130 would overrun please guide me , this is creating huge problems.
