[Geoserver-users] LDAP authentication fails with "invalid DN"

pavel.golodoniuc · February 20, 2015, 4:19am

Hi,

I'm trying to set up a layer-based LDAP authentication in GeoServer in order to leverage existing infrastructure for user and group management. I've read http://docs.geoserver.org/latest/en/user/security/tutorials/ldap/index.html and tried many configuration options but still couldn't get it to work. Numerous posts in blogs and forums reporting similar issues with LDAP authentication didn't help much. I have seen a similar issue reported earlier https://jira.codehaus.org/browse/GEOS-5999 and there was one more that I can't find anymore..

I consistently get [LDAP: error code 34 - invalid DN] error and the following gets logged in slapd syslog:

Jan 29 10:52:05 cgsrv4 slapd[3326]: conn=8628 op=0 do_bind: invalid dn ((uid=Username))

If I try to fully qualify the user lookup pattern (uid={0},ou=Users,dc=arrc,dc=csiro,dc=au) as some forum posts suggest I get the following with nothing logged in slapd logs (it looks like it doesn't even get there):

29 Jan 10:54:01 WARN [web.security] - Cannot authenticate Username
javax.naming.AuthenticationException: Cannot authenticate Username

I have logged the issue in JIRA https://jira.codehaus.org/browse/GEOS-6894 with logs and stacktraces attached. I hope this extra bit of information will help identify the issue.

Any help of suggestions where do I need to look at will be highly appreciated.

Or maybe there're other ways to set up layer based authentication. Any experiences?

CC'd the coders of this module so they'll hopefully where I've got it wrong.

Thanks for your help!

Pavel

Hi Pavel,

can you please share the configuration details for the LDAP authentication provider? A screenshot showing all the parameters you entered is fine.

Thanks
Mauro

Hi Mauro,

I have tried many different configurations but they all failed with same or very similar exceptions. I have attached a screenshot of one of the latest attempts that I’m made to JIRA issue https://jira.codehaus.org/browse/GEOS-6894. Here’s a direct link https://jira.codehaus.org/secure/attachment/67287/2015-02-24_120152.png

I tried to follow many examples that I could find on the web, including geoserver docs and others like http://geoserver.geo-solutions.it/edu/en/security/ldap_authentication.html

Thank you.

Cheers,
Pavel
