IDP Login Delay Question

[Joseph Lucia]

I changed the timeout with no additional success. My domain also does not have any child domains.

As a test I changed from SSL true to TLS true, it still hangs after the first quick login. So as an additional test I removed the bind username and password, rebooted, first login failed, but failed quickly the logs show that it needs the bind authentication, which I knew. So I closed the browser, waited couple of minutes, then tried to login again, this time it got stuck in the same place as normal for the 5 seconds before saying bad username and password.

09:20:32.478 - DEBUG [edu.vt.middleware.ldap.handler.TlsConnectionHandler:131] -   authtype = simple
09:20:32.478 - DEBUG [edu.vt.middleware.ldap.handler.TlsConnectionHandler:132] -   dn = null
09:20:32.479 - DEBUG [edu.vt.middleware.ldap.handler.TlsConnectionHandler:139] -   credential = <suppressed>
09:20:32.479 - TRACE [edu.vt.middleware.ldap.handler.TlsConnectionHandler:143] -   env = {java.naming.factory.initial=com.sun.jndi.ldap.LdapCtxFactory, java.naming.provider.url=ldap://dc3.example.com, java.naming.dns.url=dc3.example.com}
09:20:37.740 - DEBUG [edu.vt.middleware.ldap.jaas.LdapLoginModule:164] - Error occured attempting authentication

So when I use SSL, I get stuck at the Hostname verification (per the logs) and with TLS, I get stuck at the  [edu.vt.middleware.ldap.handler.TlsConnectionHandler:143].

I removed all attributes that use LDAP to rule them out, I am simply authenticating my user to Active Directory and my issue must be in login.config, but I have tried many different options, settings per the documentation and it just doesn't seem to get beyond the 5 second delay after the first login after a reboot.

I have the logs set to ALL for ldap, but I don't think there are any additional logging parameters I can set to see what is happening during that delay.

I have IDP and LDAP logs set for trace, there are no additional details for that delay outside what I have copied, I was hoping it would shed some light. I tried using those parameters from that previous thread with no luck, but I am also not using aliases and I think that was their issue, plus I am only 5 seconds compared to their 60 seconds. My wireshark is logging all traffic from the IDP server to the DC. The DC is the top domain.


When I was trying to debug ldap to AD, I had set in logging.conf:

<logger name="edu.vt.middleware.ldap" level="ALL"/>
And if I recall, TRACE messages showed up.

Are there child domains?
You may handling referrals to sub-domains.

in login.config you may want to add:

      referral="throw"
     handlerIgnoreExceptions="javax.naming.LimitExceededException,javax.naming.ReferralException"

In a data connector in attribute-resolver.xml , you may want add something like this:


    <!-- With AD DC, we throw referrals, so as not to pick up sub-domains in the forest.
         See: http://code.google.com/p/vt-middleware/wiki/vtldapAD -->
     <dc:LDAPProperty name="edu.vt.middleware.ldap.referral" value="throw"/>
     <dc:LDAPProperty name="edu.vt.middleware.ldap.handlerIgnoreExceptions" value="javax.naming.LimitExceededException,javax.naming.ReferralException"/>

I built a new IDP from scratch, CentOS6.5/Apache Tomcat/Shib IDP 2.4.0 and
I get stuck for 5 seconds in the same spot. What is interesting is the
first time you log in after a reboot there is no delay. If you log out,
close the browser and wait about 2 minutes, then log in again, it has the
login delay.

Have your tried getting a TRACE log rather then DEBUG log?

The message tread:  Re: Extremely slow IdP login<http://marc.info/?t=134389983500001&r=1&w=2>

has a number of other suggestions.

Has a solution.


Is your AD domain part of a forest? Is it the top domain?

In your Wireshark trace, were you tracing everything, or just LDAP?




13:58:27.103 - DEBUG
[edu.vt.middleware.ldap.handler.DefaultConnectionHandler:128] - Set
hostname verifier for ldaps
13:58:32.118 - DEBUG [edu.vt.middleware.ldap.ssl.AggregateTrustManager:75]
- invoking checkServerTrusted for
sun.security.ssl.X509TrustManagerImpl at 3dbb2cc9

I added the global catalog port and changed the DN login to be
username at domain.com<mailto:username at domain.com> and still no luck. I don't have a different Active
Directory to connect to for testing although if it was getting stuck
connecting to the did, I should see that in the packet capture which I am
not.

Servers being called dc (domain controller) is this MS-Active
Directory? Isn't there some issue with subtree searches from the
baseDN (and whether or not to connect to the Global Catalog port or
not)?


Lots of stuff to check/try there:
