Thanks Nathan,

  Is that documented anywhere?

Hi Carsten,

 

  I found a solution to my problem.

 

  I edited dse.ldif and set

require_secure_binds: on

allow_anonymous_access: on   (<- this is the default, I did have it set off which works fine with openldap clients).

 

I then deleted the “Enable anonymous access” ACI:

aci: (targetattr != "userPassword") (version 3.0;acl "Enable anonymous access";allow (read,compare,search)(userdn = "ldap:///anyone");)

 

and added

aci: (targetattr = "*") (version 3.0;acl "Allow Bound Users";allow (read,compare,search,selfwrite)(userdn = "ldap:///all");)

 

It would appear that the dse.ldif option “allow_anonymous_binds: off”  stops all anonymous binds to anything, including the rootdse.

Your observation is correct, but there is a third setting for nsslapd-allow-anonymous-access.  If you set it's value to "rootdse", it will only allow anonymous access to the root DSE.  Anonymous access to anything else will be denied.

 

Thanks for your help all the same,

Brett

ldapmodify -a -f <ldif> -D ...
is more recommended and
it not possible to put this aci in the dse.ldif directly.

Thanks again Carsten,

 

  To put the ACI’s in the root do I need to edit /etc/dirsrv/slapd<instance>/dse.ldif and add them there, or simply do an ldapadd ?

 

Thanks Brett

Hi,

so far I know the access to the nisdomain attribute is only necessary for the Solaris LDAP Client so that it can pull and refresh the configuration profile from LDAP-Server (refresh after TTL is expired (default 1d)). It is a marker that where the nisdomain value matched, is the right namingContex/BaseDN for search the profile. The profile is located commonly in the ou=profile container and has the objectclass=DUAConfigProfile.

But the ACI should be placed on the root entry dc=example,dc=com.

If you want to use the LDAP server Profile concept for Solaris Clients you can run /usr/lib/ldap/idsconfig.
There you must adjust the version checking, so that 389DS matches DS 5.2.

I came across this link https://blogs.oracle.com/jo/entry/anonymous_access_and_solaris_native

Which mentions adding the following ACL’s:

the baseDN- (target = ldap:///dc=example,dc=com) (targetscope = base) (targetattr="\*") (version 3.0; acl "anonymousBaseDN"; allow (read, compare, search) (userdn = "ldap:///anyone") ;) .

For super secure access, this aci could be modified thus to only allow access to thenisDomainattribute

(target = ldap:///dc=example,dc=com) (targetscope = base) (targetattr="nisdomain") (version 3.0; acl "anonymousBaseDN"; allow (read, compare, search) (userdn = "ldap:///anyone") ;) .

the profile container- (target = "ldap:///ou=profile,dc=example,dc=com") (targetscope = subtree) (targetattr="\*") (version 3.0; acl "anonymousProfile"; allow (read,compare,search) (userdn = "ldap:///anyone") ;)

For super secure access, this aci could be modified thus to only allow access to theproxyagent userobject

(target = "ldap:///cn=proxyagent,ou=profile,dc=example,dc=com") (targetscope = subtree) (targetattr="\*") (version 3.0; acl "anonymousProfile"; allow (all) (userdn = "ldap:///anyone") ;)

I just can’t figure out where to put them, any help appreciated!

Hi,

I guess it must be able for the Solaris client to read at least the base so the client can see the supported features:
# ldapsearch -h <ldapserver> -b "" -s base objectclass="*"
should return the supportedcontrols, etc.

I’ve got some hosts using Solaris 10

 

cat /etc/release

                      Solaris 10 10/09 s10s_u8wos_08a SPARC

           Copyright 2009 Sun Microsystems, Inc.  All Rights Reserved.

                        Use is subject to license terms.

                           Assembled 16 September 2009

 

Which I’ve configured with ldapclient manual (failed miserably until I allowed anonymous binds in dse.ldif).

 

ldapclient manual -vv \

-a defaultSearchBase=<blah> \

-a defaultSearchScope=sub \

-a authenticationMethod=tls:simple \

-a credentialLevel=proxy \

-a proxyDN=cn=ldapsearch,cn=config \

-a proxyPassword=<blah> \

-a serviceAuthenticationMethod=pam_ldap:tls:simple \

-a domainName=<blah> \

-a certificatePath=/var/ldap \

-a serviceSearchDescriptor=group:ou=Groups,<blah> <389 server>

 

If I turn anonymous binds off once the client is configured, it fails to connect because the Solaris client is still insisting on making anonymous binds.

I’m getting these in my access log:

 

[08/Mar/2012:15:04:49 +0100] conn=1 fd=64 slot=64 SSL connection from <Solaris 10> to <389 DS>

[08/Mar/2012:15:04:49 +0100] conn=1 op=1 fd=64 closed - U1

 

Anyone come across this before and have a solution?  I really don’t want to have to allow anonymous binds...
