Client not found in Kerberos database #3

Hi,

I have an Intel xseve 10.4.9 server bound to AD and also have OD configured
on the same server for Mac management.
Other services running are AFP and WINDOWS. I will also be using the same
server as a file server for both Mac and Windows.

Below are my issues.

When the WINDOWS service starts on our Intel Xserve with 10.4.9 installed I
receive the below error message.

I have tested single sign on "SSO" from Mac and Windows systems and
everything seems to work, but am concerned that this error may cause an
issue at a later date.

I also have an issue with windows users suddenly not being able to connect
to a share on the Intel Xserve via SMB which is strange as the same user on
a Mac could still connect via AFP or SMB a restart of the WINDOWS service
seems to clear this problem, not sure if this is related to the below error
but it's a real issue and seems to be very random. When this happen I seem
to receive "broken pipe" errors in the "smbd.conf" log.

I checked the "secrets.tdb" and found that this did not have the "\00" on
the end of the "SECRETS/MACHINE_PASSWORD/", so I ran the script at "afp548"
site under forum "10.4.8 Intel - AD, Samba kerberos machine password" which
added the "\00". The strange thing is that all seemed to still work even
thought the "secrets.tdb" was not correct, perhaps this could be the cause
of the SMB dropouts?

Below is from the SMBD.LOG

*****************

The above error occurs after I BIND the server to AD and run the "dsconfigad
�enableSSO" command and restart the server. I have tried removing the OD
configuration and BINDING to AD again but still get the above error.

The "OSXSERVER" in the log  is the OS X server name and the "REALM.EDU.AU"
is the AD realm. It seems to be related to the SMB.conf as when I change the
"netbios" name in the SMB.conf the "OSXSERVER" name changes in the SMBD.LOG.

Thanks for any help,
Regan.

Hi My overall project is to get a Debian Sarge mail/samba-server to connect with a Windows server 2003, but i'm having problem with the kerberos/LPAD connection. I started uot with this guide: http://www.enterprisenetworkingplanet.com/netos/article.php/3487081 And i got all the components (Have_KRB5_H and etc.), but no connection.. If i test the conn with: kinit administrator@DOM.NET kinit(v5): Client not found in Kerberos database while getting initial credentials And if i test with: kinit administrator@dom.net kinit(v5): Cannot resolve network address for KDC in requested realm while getting initial credentials So in general I'm having trouble defining what is what and what to install. When typing my "Kerberos server" in the conf i put in the windows-server, but should that be the linuxserver? And have much should i install on the linuxserver to make it into a "kerberos server". I already got these. libpam-krb5 krb5-user krb5-doc krb5-config krb5-kdc libkrb53 ----- krb5.conf ----------- [libdefaults] default_realm = DOM.NET [realms] DOM.NET = { kdc = WINDOWSSERVER.DOM.NET } [domain_realms] .kerberos.server = DOM.NET Hope anyone can guide me through this... /Lars ________________________________________________ Kerberos mailing list Kerberos@mit.edu https://mailman.mit.edu/mailman/listinfo/kerberos ...

Client not found in Kerberos database #4
Hi folks, My site uses Debian squeeze for both workstations and servers with MIT Kerberos 1.8.3 for authentication. Although there are generally no complaints, from time to time users say that the workstations do not accept their passwords on the first attempt, even when they anticipate the issue and made a conscious effort to not make any mistakes. Upon examination of the KDC logs, I find some evidence to support their claims. The most obvious is this error: CLIENT_NOT_FOUND: jsmith@EXAMPLE.COM for krbtgt/EXAMPLE.COM@EXAMPLE.COM, Client not found in Kerberos database In most cases the login name is not not spelled correctly, or there is nothing like it in the database at all, but in others there is nothing wrong. Yet, this error occurs anyway. Does anyone have an explanation for this phenomenon? Thanks, Jaap ...

Right. > Whoever told you 'ksu' was part of the encryption kit was mistaken, > ksu has never been part of SEAM. OK, thanks for that clarification.

MIT Kerberos KDC & W2K Client: Changing expired password issueMIT Kerberos KDC & W2K Client: Changing expired password issue
Hi, I also experienced the same problem as William G.Zereneh (http://mailman.mit.edu/pipermail/kerberos/2004-May/005341.html). I'm able to change the password using ctrl-alt-del, but when the password is expired and windows asks me to change the password, I encountered "Domain MIT.REALM.COM is not available" error. As I sniff the packet, it noticed that it sent a CLDAP query message with filter: (&(DnsDomain = MIT.REALM.COM)(Host = myhostname)(NtVer=\006) which is returned NULL by my _ldap._tcp.dc._msdcs.REALM.MIT.COM How to resolve this problem ? maybe there's a missing entry in my DNS ? Is it mandatory for the MIT Kerberos KDC (I installed it on RedHat Linux) to have an LDAP service to resolve the CLDAP request ? and can LDAP actually entertains CLDAP request since LDAP is using TCP while CLDAP is using UDP ? Can I resolve the CLDAP request using Windows 2000 server instead ? Any ideas will be very appreciated Regards from newbie, lara ===== ------------------------------------------------------------------------------------ La vie, voyez-vous, ca n'est jamais si bon ni si mauvais qu'on croit - Guy de Maupassant - ------------------------------------------------------------------------------------ __________________________________ Do you Yahoo!?

Help on Unix kerberos client->win2k3 kerberos KDC
Hello, I am a newbie to kerberos authentication, and what I am trying to do is to use a Unix ldap client authenticate to the win2k3 server, and add a user to it. The way I tried to do is by following MIT's tutorial and sample code under www.mit.edu/afs/athena/astaff/project/ ldap/AD99/kerberossamp.txt. and I configured the Unix machine based on Microsoft tutorial http://www.microsoft.com/windows2000/techinfo/planning/security/kerbsteps.asp =========> I can successfully import a tgt from win2k3 KDC server by running kinit, here is the result: $ kdestroy $ kinitPassword for mwang@SYSTEST.abc.COM: $ klist Ticket cache: FILE:/tmp/krb5cc_1023 Default principal: mwang@SYSTEST.abc.COM Valid starting Expires Service principal 10/31/03 17:53:08 11/01/03 03:50:48 krbtgt/SYSTEST.abc.COM@SYSTEST.abc.COM renew until 11/01/03 17:53:08 Kerberos 4 ticket cache: /tmp/tkt1023 klist: You have no tickets cached ===========> Then I tried to run adduser program, I made a little change to the code to set some default values.

Server not found in Kerberos database #2
Hi, I'm a Java developer and new to Kerberos. We have a Java application that needs to be authenticated against Kerberos Active Directory. For testing purpose, we have Active Directory installed on a Win 2k server. Then, the Kerberos was turned on by a co-worker, who doesn't know much about Kerberos either. Without any manual about Active Directory, he did that based on his best judgement. Here are the basic setting information: (01) The Win2k server has FQDN: devtest.mycompany.com. (02) C:\WINNT\krb5.ini file looks like: [libdefaults] default_realm = DEVTEST.COM [realms] DEVTEST.COM = { kdc = <IP address of the Win2k server> } (03) The AD is listening on port 389 (default for LDAP server), and KDC listens on port 88. When a user logs in with Java code, apparently the user can log in successfully and get ticket from Kerberos AD. However, whenever the code tries to instantiate InitialDirContext (an Object in Java that would capture the environment context), an error would be thrown claiming that "Server not found in Kerberos database". I can't find problem in the Java code and suspect the error may be related with our Kerberos setting. I wonder what exactly the error message means in Kerberos arena. How can I verify that the Kerberos is correctly set? Also, you may notice that the Kerberos realm (DEVTEST.COM) is not the same as the machine's FQDN (devtest.mycompany.com). I wonder if that makes any difference. Our code-...

Newbie: "Server not found in Kerberos database"
I am still in 'toy installation mode'. I have set up a KDC on a Linux machine, call it kervara.mygroup.org I have successfully set things up to the point that I can kinit from various clients. I have also set up OpenSSH 3.9p1 to use GSSAPI authentication. When I am logged into kervara, and have a valid TGT from this realm, I can successfully ssh into kervara.mygroup.org without a password; the keytab contains entries for the host/kervara.mygroup.org principal. This is the way things are supposed to work. Life is good. The problem comes when I attempt to do the same thing with the same version of OpenSSH built with the same options on a Solaris machine. In that case, the server logs a "Server not found in Kerberos database" message and gives up. I have looked at all the obvious candidates (wrong DNS entry, disagreement as to host name in /etc/hosts and DNS, etc) and come up empty. Unfortunately, the log messages do not tell me _what_ principal it was trying to find in krb5.keytab (I assume that this is where the mismatch or missing entry is). Is there a way to squeeze more diagnostic information? Or does this sound like a familiar problem?

hello, I have added to my kerberos database the following principal: "http://localhost:8080/axis/services/test" . (It' s in a url format instead of being in the format: service/host@REALM.) So, the thing is that I would like to acquire a service ticket for that principal. To request a service ticket I am using gss api and follow the next steps: class KrbClient{ main(){ ..... //I have acquired the credentials from the ticket cache .... PrincipalName serviceName = new PrincipalName("http://localhost:8080/axis/services/test"); // create the tgs_req to ask for service tickets sun.security.krb5.KrbTgsReq tgs_req = new sun.security.krb5.KrbTgsReq(credentials, serviceName); tgs_req.send(); // get tgs_rep KrbTgsRep tgs_rep = tgs_req.getReply(); } } and it gets the folllowing error: KrbException: Server not found in Kerberos database (7) at sun.security.krb5.KrbTgsRep.<init>(KrbTgsRep.java:67) at sun.security.krb5.KrbTgsReq.getReply(KrbTgsReq.java:235) at KrbClient.requestServiceTicket(KrbClient.java:142) at KrbClient.main(KrbClient.java:39) Caused by: KrbException: Identifier doesn't match expected value (906) at sun.security.krb5.internal.KDCRep.init(KDCRep.java:134) at sun.security.krb5.internal.TGSRep.init(TGSRep.java:59) at sun.security.krb5.internal.TGSRep.<init>(TGSRep.java:54) at sun.security.krb5.KrbTgsRep.<init>(KrbTgsRep.java:50) ... 3 more >From the debugging of gss api: >>>KRBError: sTime is Mon ...

Kerberos for AIX 4.3.3
I'm trying to install Kerberos for AIX 4.3.3 so we can authenticate to a Windows 2003 AD domain, but I'm having a devil of a time trying to get it. Could anyone direct me to it's location, on install media or online? I hear that it is contained in the DCE package, but that is not installed on the box I've been assigned to work on. Thanks, Robert Wicks ...

newbie: error getting credentials: Server not found in Kerberos database
Hi! I never found the time to deal intensively with kerberos so please indulge me if this is ought to be a stupid question: kinit works. krsh does not: krsh server error getting credentials: Server not found in Kerberos database trying normal rlogin (/usr/bin/rlogin) So, this is what I did so far: server: /etc/krb5.conf: [libdefaults] default_realm = LOCALDOMAIN [realms] LOCALDOMAIN = { kdc = server.localdomain:88 admin_server = server.localdomain:750 } [domain_realm] .localdomain = LOCALDOMAIN localdomain = LOCALDOMAIN [logging] kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmin.log default = FILE:/var/log/krb5lib.log /etc/hosts: 127.0.0.1 localhost 192.168.0.2 server server.localdomain real hostname is actually *not* "server"! kadmin.local: addprinc foo client: /etc/krb5.conf [libdefaults] ticket_lifetime = 600 default_realm = LOCALDOMAIN default_tkt_enctypes = des3-hmac-sha1 des-cbc-crc default_tgs_enctypes = des3-hmac-sha1 des-cbc-crc [realms] LOCALDOMAIN = { kdc = server.localdomain:88 admin_server = server.localdomain:750 } [domain_realm] .localdomain = LOCALDOMAIN localdomain = LOCALDOMAIN [kdc] profile = /etc/krb5kdc/kdc.conf [logging] kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmin.log default = FI...
