RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description German Parente 2018-05-23 14:13:15 UTC
Description of problem:

I have configured passthrough plugin to do Starttls:


nsslapd-pluginarg0: ldap://nslcd.parente.local:1389/dc=parente,dc=local 3,5,30
 0,3,300,1


I have added plugin debug logs. To have that login, I had to define this in source code and re-build:

#define    PASSTHRU_VERBOSE_LOGGING 

Then I see clearly:

passthru-plugin - PTA server host: "nslcd.parente.local", port: 1389, secure: 2, maxconnections: 3, maxconcurrency: 5, timeout: 300, ldversion: 3, connlifetime: 300

secure: 2 means starttls:


        if (starttls) {
            srvr->ptsrvr_secure = 2;
        }


bind as:

ldapsearch -D "uid=omc,ou=people,dc=parente,dc=local" -w secret12 -b "dc=parente,dc=local" -s base


But in the access logs, we see clearly:

[23/May/2018:10:07:20.883924603 -0400] conn=1 fd=64 slot=64 connection from 10.10.178.222 to 10.10.178.222
[23/May/2018:10:07:20.884685945 -0400] conn=1 op=0 BIND dn="uid=omc,ou=people,dc=parente,dc=local" method=128 version=3
[23/May/2018:10:07:20.886823710 -0400] conn=1 op=0 RESULT err=0 tag=97 nentries=0 etime=0.0002572394 dn="uid=omc,ou=people,dc=parente,dc=local"

No startls.

Now, in the code, when parsing the url:

    /* use secure setting from url if none given */
    if (!secure && ludp) {
        if (secureurl) {
            secure = SLAPI_LDAP_INIT_FLAG_SSL;
        } else if (0 /* starttls option - not supported yet in LDAP URLs */) {
            secure = SLAPI_LDAP_INIT_FLAG_startTLS;
        }
    }

So, I wonder if the problem is not that the starttls is not supported in ldap urls but ... in the passthrough plugin we cannot but specify ldapurl

Comment 11 Akshay Adhikari 2018-08-10 11:04:13 UTC
Build Tested: 389-ds-base-1.3.8.4-9.el7.x86_64
 
Note: Target server is the machine on which SSL is configured and source server is the one on which passthrough plugin is configured.
 
1) Configure passthrough plugin to do starttls:
   dn: cn=Pass Through Authentication,cn=plugins,cn=config
   changetype: modify
   replace: nsslapd-pluginarg0
   nsslapd-pluginarg0:  ldap://<hostname>:<ldap_port>/dc=example,dc=com 3,5,300,3,300,1
 
2) Set nsslapd-pluginEnabled to ON.
 
3) Restart the source server.
 
4) Add a user under the suffix "dc=example,dc=com".
 
5) Add the CA certificate from Target machine to the source.
 
6) Restart the source server.
 
Results:
