LDAPS fails with "No trusted certificate found"

betawayoflife — Wed, 29 Apr 2020 06:30:22 GMT

Hi,

heres the ldaps setup:

1.) Export Root-CA Cert to C:\etc\rootca.cer

2.) Create keystore:

E:\Alfresco6\java\bin\keytool -importcert -alias rootca -file "C:\etc\rootca.cer" -keystore "E:\Alfresco6\alf_data\keystore\rootca.keystore" -storepass xxxxx -storetype JCEKS

3.) LDAP Properties:

ldap.authentication.java.naming.provider.url=ldaps://dc01.domain.loc
ldap.authentication.truststore.path=${dir.keystore}/rootca.keystore
ldap.authentication.truststore.passphrase=xxxxx
ldap.authentication.truststore.type=JCEKS
ldap.authentication.java.naming.security.protocol=ssl

4.) Tomcat Settings:

-Dcom.sun.jndi.ldap.object.disableEndpointIdentification=true

See https://issues.alfresco.com/jira/browse/MNT-21030

So far so good.... Now the strange thing.

If i restart alfresco the ldap sync works for ~ 1 out of 10 trys.... 9 trys fails with "No trusted certificate found"
Any ideas?

Heres the stacktrace:

Hi,

I don"t have an answer for you but just want to say that i've got the same problem. Sometimes synch works but most of the time not. Hope that someone will have a solution. I'll let you know if i found something.

My setup;

-alfresco 6.0.1

-ldaps with windows active directory

Regards

Marc

Hi,

For myself, it's working w/o errors for 2 days now.

Here's what i did.

- Add this in java: -Dcom.sun.jndi.ldap.object.disableEndpointIdentification=true

-import root CA certificate to the keystore with keytool. Now keystore contains ldaps certificate and CA certificate.

Hope that this would help you. I will let this running for the next days and see if it will hold on

Regards,

Marc

Hi,

i did it like this:

E:\Alfresco6\java\bin\keytool -importcert -alias domain.loc -file "C:\etc\rootca.cer" -keystore "E:\Alfresco6\alf_data\keystore\rootca.keystore" -storepass xxxxx -storetype JCEKS

In the Tomcat options i added this:

-Dcom.sun.jndi.ldap.object.disableEndpointIdentification=true

My settings are like this:

ldap.authentication.java.naming.provider.url=ldaps://dc01.domain.loc:636
ldap.authentication.truststore.path=${dir.keystore}/rootca.keystore
ldap.authentication.truststore.passphrase=xxxxx
ldap.authentication.truststore.type=JCEKS
ldap.authentication.java.naming.security.protocol=ssl

Why does i need the ldaps cert? Isn't the root cert enough?
The ldaps cert is every year a new one in an active directory environment...

Thanks, Joe

Solved.

Because of the bug MNT-21030 (mentioned in my first post) LDAPS uses "domain.loc:636" for the ldap bind.

I only configured one dc with a correct certificate, but i've 7 dc's running.
The dns resolution for "domain.loc" is round-robin, so ~ 1/7 of the syncs was working.

Now i configured all dc's and it's running fine.
