similar to: nscd crashes

Again, another confusing issue in two how-to's I'm trying to resolve. In the SBE (samba-3 by example) Pg 161 in the PDF states. (It's actually page 200 of the PDF, but 161 of the numbered document pages.) "The name service caching daemon (nscd) is a primary cause of difficulties with name resolution, particularly where winbind is used." But the Authconfig in the IDEALX

Hi, I'd like to use nscd for passwd+group caching. pam_ldap is configured and works (e.g. 'id foo' returns the correct user id if foo is present in ldap). If I start nscd manually (not started by default), 'id foo' returns 'No such user'. As soon as I stop nscd, 'id foo' starts working again. I suspect nscd is only looking at /etc/passwd because 'id

Does anyone know if there is a fix for nscd segfaulting after a short period of time. Googling for it came up with one result that suggested deleting the files in /var/db/nscd , but that didn't help. Another result was about run away processes which is not the problem I'm having. They are x86_64 boxes. output from /var/log/messages Oct 9 12:56:38 lyra kernel: nscd[11660]: segfault at

Hi all, I have set up nscd on my CentOS 5 box with nss_ldap. getent shows all LDAP groups correctly but 'id' only shows the users primary group. Best Regards Marcus

Dear samba folks, I have a special question regarding the simultaneous operation of nscd and winbindd on the same host: We are running in a Samba file server setup where the nsswitch.conf looks like this: passwd: files ldap group: files ldap shadow: files ldap hosts: files dns wins networks: files protocols: db files services: db files

Dear All, I'm thinking about connecting the 15 or so laptops in our organisation to LDAP. Now I'm trying to use nscd in order to enable the users to work when being offline. The test laptop is installed for this occasion, updated CentOs6.3. Following the advise I found on a few posts I modified */etc/nscd.conf : * server-user nscd logfile

Has anyone had problems accessing random websites since going up to 6.4? Since about the day after I got partly upgraded, if I try to access nytimes.com, or orbitz.com, I get server not found. With a lot of work, I, my manager, and the other admin, found that setting options edns0 in /etc/resolv.conf fixed it - I suspect that the network folks updated their internal nameservers (which are M$)

Hi Everyone, the new 3.0.4 Samba installation seems to work find except that from time to time but at least a couple of times a day one or more smbd processes start running at 20%-40% CPU each and 6 nscd processes then share the remaining CPU power. System 70%-80% users the rest 20%-30%. Load rises fast to over 4. I'm sure that each such process is just idling, but why does it engage so much

Hi All, I just enabled nscd to see if I can speed up some operations on our large NFS/NIS environment, however, now that I've enabled nscd I am no longer able to sudo. Can someone please point me in the right direction? Everything was working fine prior to enabling it. -- James A.

Hi, I'm using Samba 3 as a PDC with an Openldap backend and also have a number of Samba domain member servers that lookup the ldap directory for their account information. I use ssh to perform various administration tasks. There is an account called Administrator in the LDAP directory that has a UID of 0 . However, after nscd has been started, the next time i login to one of the member

I finally ran across the following post: http://lists.samba.org/archive/samba/2006-May/120798.html Turns out my earlier post to this list for help stems from the NSCD problem like this person had. I changed the negative TTLs in nscd.conf to 3s and changed the -t argument to 15 in my add machine script. This solved my join domain problem. Before all this, NSCD was not running. When NSCD is

I'm (finally) getting around to putting a backup LDAP authentication server on my network. The backup uses syncrepl to grab the database, and to my eyes both LDAP servers answer read queries identically. I'm testing the client side of this configuration on virtual CentOS 5 i386 machine. /etc/ldap.conf reads ----- %< ----- base dc=DOMAIN,dc=com timelimit 30 bind_timelimit 30

Hi We have installed and configured Samba 2.2.8 on a Solaris (Sparc) 8 server recently. This server is to replace an existing member server in a NT4 domain and will act as a file server. We want to perform as little user maintenance on the Solaris side as possible so that most of the user setup and maintenance for the domain is controlled through a NT4 server using usrmgr and want to use NT

Hi, This email is a follow-up to my previous email about "Postfix: user unknown", perhaps these are related. Every time I restart openldap i get an error message from nscd: --- May 15 14:53:02 mail nscd: nss_ldap: could not search LDAP server - Server is unavailable --- This is due to a timeout, correct? Here is part of my /etc/ldap.conf --- timelimit 120

Hi. I'm trying to setup an OpenLDAP server on MandrakeLinux 8.2 for use with Samba. To accomplish this, I'm using the idealx Samba LDAP howto. It says to use "authconfig" to setup the system to use pam_ldap, nss_ldap and nscd. I don't have Red Hat and thus don't have authconfig. Translated to config files, what does authconfig do? Thanks, Alexander Skwar -- How to

Hi, I'm having a problem with this setup: RHEL4 U4.2(Centos) + openldap + nscd The problem I see is that for some reason, after a couple of hours dovecot stuck in the auth procress. I do a : telnet localhost imap Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. 1 login user pass (here is the delay) After passing a username/password, the
