Hi I was having odd issues with my IPA domain so rather than troubleshoot it properly I thought it would be a good idea to remove it and then add it again.

I removed it with engine-manage-domains -action=delete -domain=clarkconnect.lan

and when I try to add it with engine-manage-domains -action=add -domain=clarkconnect.lan -user=admin -provider=IPA -interactive

which worked fine the first time I get

in the engine-manage-domains.log I get

Details: %2$s: One of the parameters for this error is null and no default message to show

any ideas?

We have seen a similar issue with OpenLDAP that required to set the minimum security strength factor (SSF) to 1 instead of the default 0. This default triggers a bug in the Java virtual machine Kerberos support.

IPA uses the 389 directory server, and it also has the possibility to configure this, as described here:

http://directory.fedoraproject.org/wiki/Minimum_SSF_Setting

To check that you can run a query like this in your IPA installation:

# kinit admin # ldapsearch \ -H ldap://your_ipa_server \ -Y GSSAPI \ -LLL \ -b 'cn=config' \ -s base \ nsslapd-minssf

The output will probably be like this:

dn: cn=config nsslapd-minssf: 0

The important thing there is the value 0. You can try to change it to 1, via LDAP or modifying directly the file /etc/dirsrv/slapd-YOUR-REALM/dse.ldif. Do this with the directory server stopped, and remember how to revert it in case things fail.

Let us know if this helps.

By the way, for those interested in how to change this in OpenLDAP, it requires something like this:

# cat > fixssf.ldif <<'.' dn: cn=config replace: olcSaslSecProps olcSaslSecProps: noanonymous,noplain,minssf=1 - .

# ldapmodify -H ldapi:/// -Y EXTERNAL -f fixssf.ldif

That did the trick. I edited the file as I had no hope of getting an ldapmodify command going on my own. That's why I installed IPA in the first place. :) -- Junk. ------OSDCNA0F0ZP8RJNEPTMP6K3VSHMEQ5 Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: 8bit <html><head></head><body><div class="gmail_quote">Juan Hernandez <jhernand@redhat.com> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> <pre class="k9mail"><br />On 11/13/2013 10:11 PM, Junk wrote:<br /><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;">Hi I was having odd issues with my IPA domain so rather than<br />troubleshoot it properly I thought it would be a good idea to remove it<br />and then add it again.<br /><br />I removed it with <br />engine-manage-domains -action=delete -domain=clarkconnect.lan<br /><br />and when I try to add it with <br />engine-manage-domains -action=add -domain=clarkconnect.lan -user=admin<br />-provider=IPA -interactive<br /><br />which worked fine the first time I get<br /><br />General error has occurednull<br />java.lang.NegativeArraySizeException<br /> at<br />sun.security.jgss.krb5.CipherHelper.aes256Encrypt(CipherHelper.java:1367)<br /> at<br />sun.security.jgss.krb5.CipherHelper.encryptData(CipherHelper.java:722)<br /> at sun.security.jgss.krb5.WrapToken_v2.<init>(WrapToken_v2.java:200)<br /> at sun.security.jgss.krb5.Krb5Context.wrap(Krb5Context.java:861)<br /> at sun.security.jgss.GSSContextImpl.wrap(GSSContextImpl.java:385)<br /> at com.sun.security.sasl.gsskerb.GssKrb5Base.wrap(GssKrb5Base.java:104)<br /> at<br />com.sun.jndi.ldap.sasl.SaslOutputStream.write(SaslOutputStream.java:89)<br /> at com.sun.jndi.ldap.Connection.writeRequest(Connection.java:430)<br /> at com.sun.jndi.ldap.LdapClient.search(LdapClient.java:555)<br /> at com.sun.jndi.ldap.LdapCtx.doSearch(LdapCtx.java:1985)<br /> at com.sun.jndi.ldap.LdapCtx.searchAux(LdapCtx.java:1847)<br /> at com.sun.jndi.ldap.LdapCtx.c_search(LdapCtx.java:1772)<br /> at<br />com.sun.jndi.toolkit.ctx.ComponentDirContext.p_search(ComponentDirContext.java:386)<br /> at<br />com.sun.jndi.toolkit.ctx.PartialCompositeDirContext.search(PartialCompositeDirContext.java:356)<br /> at<br />com.sun.jndi.toolkit.ctx.PartialCompositeDirContext.search(PartialCompositeDirContext.java:339)<br /> at<br />javax.naming.directory.InitialDirContext.search(InitialDirContext.java:267)<br /> at org.ovirt.engine.core.ldap.RootDSEData.<init>(RootDSEData.java:52)<br /> at<br />org.ovirt.engine.core.utils.kerberos.JndiAction.getDomainDN(JndiAction.java:257)<br /> at<br />org.ovirt.engine.core.utils.kerberos.JndiAction.run(JndiAction.java:87)<br /> at java.security.AccessController.doPrivileged(Native Method)<br /> at javax.security.auth.Subject.doAs(Subject.java:356)<br /> at<br />org.ovirt.engine.core.utils.kerberos.KerberosConfigCheck.promptSuccessfulAuthentication(KerberosConfigCheck.java:174)<br /> at<br />org.ovirt.engine.core.utils.kerberos.KerberosConfigCheck.validateKerberosInstallation(KerberosConfigCheck.java:150)<br /> at<br />org.ovirt.engine.core.utils.kerberos.KerberosConfigCheck.checkInstallation(KerberosConfigCheck.java:135)<br /> at<br />org.ovirt.engine.core.domains.ManageDomains.checkKerberosConfiguration(ManageDomains.java:746)<br /> at<br />org.ovirt.engine.core.domains.ManageDomains.testConfiguration(ManageDomains.java:917)<br /> at<br />org.ovirt.engine.core.domains.ManageDomains.addDomain(ManageDomains.java:539)<br /> at<br />org.ovirt.engine.core.domains.ManageDomains.runCommand(ManageDomains.java:311)<br /> at<br />org.ovirt.engine.core.domains.ManageDomains.main(ManageDomains.java:206)<br /> at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)<br /> at<br />sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)<br /> at<br />sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)<br /> at java.lang.reflect.Method.invoke(Method.java:606)<br /> at org.jboss.modules.Module.run(Module.java:260)<br /> at org.jboss.modules.Main.main(Main.java:291)<br />Failure while testing domain %1$s.

how about wikifyig this under 'troubleshooting manage-domains' or something like that?

I was stumped by this as well, but Juan's fix resolved the issue. I added this to the wiki: http://www.ovirt.org/Troubleshooting#Adding_an_IPA_domain_to_ovirt_engine
