Hi All, I've been growing a large headache on this one, i have a number of LDAP servers behind loadbalancing, since 2 days i constantly get the error: Too many open files. Although I'm not a newbie with linux I'm unable to resolve this, I have took the following stept: Changed the /proc/sys/fs/file-max to 65535 Added the following configuration to /etc/security/limits.conf: ldap

Samba 4.1.16, Centos 6.6 x86-64, BIND_DLZ 9.9. I have three AD DC's that were functioning normally. However, today I restarted BIND on one node, and it failed to start with this message in the log (names changed): May 10 07:02:49 benford named[6767]: Loading 'AD DNS Zone' using driver dlopen May 10 07:02:49 benford named[6767]: samba_dlz: started for DN DC=samdom,DC=example,DC=com May

Roland, Thank you very much for your attention to this. You should get a medal for all the help you give everyone on this list. On Sun, 10 May 2015, Rowland Penny wrote: > Why ? And why don't they show up when you ask for the zones with samba-tool ? I have that many subnets. As for why they don't show up: they are defined in BIND's configuration and not samba's; they never

This idea is intruiging... Suppose one has a set of file servers called A, B, C, D, and so forth, all running CentOS 6.5 64-bit, all being interconnected with 10GbE. These file servers can be divided into identical pairs, so A is the same configuration (diks, processors, etc) as B, C the same as D, and so forth (because this is what I have; there are ten servers in all). Each file server has

OK, I had this working a few days ago, but have evidently changed something that I cannot locate. Someone hit me with their 2x4. Samba 3.0.22, Fedora Core 4, ldapsam (OpenLDAP 2.3.24). smbd will not start, with the "ERROR: failed to setup guest info" error (I have "guest account = guest", which is a valid user with correct info in LDAP): ldap_connect_system: Binding to ldap

New samba deployment; samba 3.0.24 w/ldapsam, em64t (Dell 2900), CentOS 4.4, using nss_ldap with LDAP master and two slaves (OpenLDAP 2.3.32), one Samba PDC (on LDAP master) and two Samba BDC's (on each of the LDAP slaves); no Windows servers; one Linux domain member server (first of several). All four Samba servers use the same LDAP parameters. testparm checks out. All accounts are in

Hi I have configured a machine to authenticate against LDAP. When I log onto the box using the newly created user I see a LDAP search request for every user that exist in the directory. If I have only 20 users even a 100 that is not a problem but when I start going to 10000 users I start getting some weird errors and timeouts because of the time it takes to download the data to the client. I

Hi, I have two 320 GB SATA disks (/dev/sda, /dev/sdb) in a server running CentOS release 5. They both have three partitions setup as RAID1 using md (boot, swap, and an LVM data partition). # cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdb1[1] sda1[0] 104320 blocks [2/2] [UU] md1 : active raid1 sdb2[1] sda2[0] 4192896 blocks [2/2] [UU] md2 : active raid1 sdb3[1]

I have a client with a handful of USB drives connected to a CentOS box. I am charged with binding the USB drives together into a single LVM for a cheap storage data pool (10 x 1 TB usb drives = 10 TB cheap storage in a single mount point). The next fun piece is how to incorporate that storage space into an existing Active Directory structure to apply AD acls for limited access. I'd rather

This is samba's: dlz "AD DNS Zone" { database "dlopen /mnt/domain/samba/europa/lib/bind9/dlz_bind9_9.so"; }; and this is BIND's (notice the last line commented out): options { directory "/var/named"; dump-file "/var/named/data/cache_dump.db";

Short story: cannot get Kerberized NFSv4 to work. I've googled a great deal and cannot find where I have goofed (and there sure is a lot of misleading and just plain incorrect information out there), so would appreciate another pair of eyes. NFSv4 without Kerberos does work fine, as does ID mapping. We're using NFSv4 in production with sec=sys, but I'm not happy with that. My

I could use some input to point out the error in my configuration, which eludes me. Previously I operated a 225-node cluster with samba 4.3 and sssd on the Linux boxes. Everything worked OK. Now I am using samba 4.11.6 on CentOS 7.7, patched up to date. The DC, on a KVM VM, is the only node configured so far. I am using winbind in place of sssd (my first experience with winbind). BIND9_DLZ

In CentOS 5.7 and earlier versions, an alias interface is defined via ifcfg-<interface>:foo which contains "ONBOOT=no". The ONBOOT setting appears to be ignored, and the interface always starts when the system boots or if networking is restarted. This is a serious bug that seems to date back many years (I found references in 2005). Anyone know why it hasn't been fixed, or

Samba 4.0.0beta4, CentOS 6.3 (openldap 2.4.23-26.el6), samba-generated krb5.conf. I have joined a Linux client to the samba4 domain and extracted the kerberos5 keytab (using "kerberos method = system keytab"): # kinit Administrator (succeeds) # net ads join createupn=host/<client.fqdn>@REALM -k (succeeds) # net ads keytab create (succeeds) # net ads testjoin (is OK) #

Samba 4.1.1 using BIND_DLZ (bind-9.9.1-0.1.P2) on CentOS 6.5 x86_64. I have two domain controllers, dc-1 and dc-2, which each have three network interfaces. Selinux is in permissive mode, and iptables is off. One interface on each dc is to be shut down. So, on dc-1, I do: # nsupdate -g update delete europa.icse.cornell.edu A 192.168.3.250 update delete europa.icse.cornell.edu A 192.168.3.251

I checked on the original DC before I demoted it, and there were only 5 displayed, so I thought that was all I should have. At least, I transferred -all roles, and only those 5 made it. This is going to be a pain to
