Artifactory uses a 10 second connection timeout to the LDAP server by default. 10 seconds for timeout is sufficient in most cases, and we would strongly suggest to see why the timeout between the Artifactory and the LDAP server is occurring from time to time. If LDAP search does not return result in 10 seconds, Artifactory will through an error similar to below:
[ERROR] (o.a.a.l.p.LdapGroupProviderImpl:190) – An error occurred while retrieving LDAP groups with strategy STATIC, org.springframework.ldap.UncategorizedLdapException: Uncategorized exception occured during LDAP processing; nested exception is javax.naming.NamingException: LDAPresponse read timed out, timeout used:10000ms.; remaining name 'ou=exchange_objects,dc=joshuanet,dc=global,dc=joshua,dc=com'
When the timeout issue happens, your Artifactory server could be failing to get a response from your LDAP server for more than 10 seconds. Please verify this by checking your network between the Artifactory server and the LDAP server when this issue happens. You may run a network trace between them to expedite the investigation.
Also, please consider narrowing down your Artifactory LDAP search base by using "Search Base" in Artifactory's LDAP setting. The Search Base in Artifactory is the context name in which to search relative to the base DN in the LDAP URL. Please see our Wiki for details, and consult your LDAP administrator for assistance.
Or, you may increase the LDAP socket timeout value set at artifactory.system.properties, for example to 20 seconds (20000 ms)
Please note that you need to restart Artifactory after making the change.
Please note that we recommend using Artifactory's native user for CI builds instead of LDAP user for builds for following reasons:
– Faster than LDAP logins
– Password is not changed by LDAP Password policies
