Problem with "force user to password reset at first login
by Rajagopal Rc
Hi,
I am trying to force users to change their password at first login or
after
password reset by administrator.
Tried following:
1)Password policy 'pwdMustChange TRUE' doesn't seems to be working as non
of the
users get prompt to change their password at first login.
2) used the 'pwdReset TRUE' attribute in users attributes, and it won't
prompt
to change the password and didn't allow to login
i observe below messages in log
"slapd[12684]: connection restricted to password changing only
slapd[12684]: send_ldap_result: err=50 matched="" text="Operations are
restricted to bind/unbind/abandon/StartTLS/modify password"
slapd[12684]: conn=1053 op=1 SEARCH RESULT tag=101 err=50 nentries=0
text=Operations are restricted to bind/unbind/abandon/StartTLS/modify
password"
Please help me configure the option to force all users to change their
password
at first login or after pwd reset by administrator.
Thanks & Regards
Raj

slapd-meta
by Fr3ddie
Hello to the list,
I'm trying to configure the slapd-meta OpenLDAP backend on an online
cn=config
configuration with no luck. Slapd version is 2.4.39 (the maximum I can
achieve on the target machines building from vanilla source).
The documentation is clear but too concise for me so I will try to explain
what I'm trying to do to see if there is anybody that can help me.
Currently I have 3 slapd servers that share a common root for the DIT, i.e.:
dc=loc1,dc=root
dc=loc2,dc=root
dc=loc3,dc=root
What I would like to achieve is to obtain a fourth server that contains
the previous trees, along with its own tree, i.e. a server that contains:
dc=loc0,dc=root (locally hosted data)
dc=loc1,dc=root (coming from the first server, chasing referrals)
dc=loc2,dc=root (coming from the second server, chasing referrals)
dc=loc3,dc=root (coming from the third server, chasing referrals)
this way, all the clients connecting to this server will be able to
retrieve data also from the other three remote servers.
As far as I understood, I only need to configure the "loc0" server to access
the other three servers and get the data to serve to clients.
I have already configured the fourth server with its local DIT and this is
the configuration:
# cat 'cn=config.ldif'

On top of this DB I have the "syncprov" and the "accesslog" overlays
configured
(these are two servers in "MirrorMode", configured following the
OpenLDAP admin documentation).
I believe this DB is the ones containing the actual "loc0" DIT data...
Then I have the accesslog DB for the replica (with the syncprov overlay
on top):
# cat 'olcDatabase={2}hdb.ldif'
dn: olcDatabase={2}hdb
objectClass: olcDatabaseConfig
objectClass: olcHdbConfig
olcDatabase: {2}hdb

olcDbConfig: {4}set_flags DB_LOG_AUTOREMOVE
olcDbIndex: default eq
olcDbIndex: entryCSN,objectClass,reqEnd,reqResult,reqStart
[...]
On top of this environment I start loading the needed modules with this
LDIF file:
version: 1
dn: cn=module{0},cn=config
changetype: modify
add: olcModuleLoad
olcModuleLoad: back_ldap
-
add: olcModuleLoad
olcModuleLoad: back_meta
-
add: olcModuleLoad
olcModuleLoad: rwm
and it seems I'm able to load the new modules without errors
into the configuration, thus I obtain:
# cat 'cn=module{0}.ldif'
dn: cn=module{0}
structuralObjectClass: olcModuleList
objectClass: olcModuleList
cn: module{0}
olcModulePath: /usr/lib/ldap
olcModuleLoad: {0}back_hdb
olcModuleLoad: {1}syncprov
olcModuleLoad: {2}accesslog
olcModuleLoad: {3}back_ldap
olcModuleLoad: {4}back_meta
olcModuleLoad: {5}rwm
[...]
Now I try to load the slapd-meta directives into a new database using
this LDIF:
version: 1
dn: olcDatabase={3}meta,cn=config
objectClass: olcDatabaseConfig
objectClass: olcMetaConfig
olcDatabase: {3}meta
olcSuffix: dc=root
olcDbURI: "ldap://server-loc1.loc1.root/dc=loc1,dc=root"
olcDbIdAssertBind: bindmethod=simple

olcDbIdAssertBind: bindmethod=simple
binddn="cn=admin,dc=loc3,dc=root" credentials=xxxxxx starttls=yes
tls_reqcert=demand
but I obtain an error that sticks me trying various combinations without
success:

Into the slapd-meta documentation the "URI" directive is mentioned but
the "DbURI" seems to
raise a "better error", in fact if I try to modify the above LDIF file
using "URI" I obtain:
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
adding new entry "olcDatabase={3}meta,cn=config"
ldap_add: Undefined attribute type (17)
additional info: olcUri: attribute type undefined
Moreover, it is not stated into the slapd-meta docs that the slapd-ldap
backend is needed by slapd-meta but,
anyway, I think its needed because if I try to load the slapd-meta alone
it raises an error (I don't remember exactly which one).
At this point I'm stuck to this error and I wasn't able to find any hint
on the web to solve this :(
The examples I was able to find were related with the static slapd.conf
configuration, I counldn't
find any "full" configuration example using the cn=config.
I'm wondering if I should create a "cn=root" actual DB first and then
link the sub-DITs to it,
or, maybe, add some other overlay... I really can't understand how it
should work :(
Can please anybody help me?
Thank you very much

chaining for a single backend?
by Marc Patermann
Hi,
I want to activate chaining for a single backend.
The server is a replication consumer and has a few glued database backends.
Only one is containing linux accounts with ppolicy overlay.
This should use chaining to replicate the ppolicy changes which
otherwise stay local.
Can this be achieved?

problem with slapadd in migrating LDAP servers
by k j
Hello to all.
My situation is the following.
Migrating from an older Suse server : # rpm -qa | grep -i openldap openldap2-2.4.12-7.19.1 openldap2-client-2.4.12-7.19.1
to a New RHEL 6.6 server: # rpm -qa |grep ldap mod_authz_ldap-0.26-16.el6.x86_64 sssd-ldap-1.11.6-30.el6_6.4.x86_64 apr-util-ldap-1.3.9-3.el6_0.1.x86_64 openldap-clients-2.4.39-8.el6.x86_64 openldap-2.4.39-8.el6.x86_64 openldap-servers-2.4.39-8.el6.x86_64 compat-openldap-2.3.43-2.el6.x86_64
My exported information looks to be in order, has 47,000 lines but when I try to import it I run into trouble.
ldapadd -x -D "cn=administrator,dc=mydomain,dc=com" -W -f nis.ldif.ldapDump
When prompted for a password I am using the password from the old server (Suse) and that fails, thinking that no password has been setup on the new server I tried an empty password and that also failed.
Next I tried setting a new password 'ldappasswd Testing123' but that gave a SASL failure GSSAPI error :( additional info: SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Ticket expired)
Am I going down the wrong road or what?
Thanks for any help,KJ

I was afraid you were going to ask that. We are running the Redhat 6
supported 2.4.40-7.el6_7. We have a policy here of sticking with the
redhat supported releases of packages since our staff is so small.
I really need to resolve this for an important project here. Of course the
project is behind schedule and I am left with little time to get my stuff
working. I was hoping my syntax was just incorrect. The only other way I
can image fixing this is to revert to slapd.conf ....
I guess the good news is that my steps and syntax look okay to you. If you
have any other thoughts I would happily accept them.
Thanks,
Kathy

Re: [OpenLDAP][Authentication] SASL
by Timothy Keith
My scenario is relatively simple. The user authentication and LDAP
directory for our local application is managed on corporate servers
for which we lack administrative rights. We wish to maintain a local
view of the LDAP directory for the information that our local
application requires, but not alter the user authentication on the
corporate servers.

openldap and slapd.conf file
by Mary Kao
Hello,
I've seen information indicating that slapd.conf is no longer in use in OpenLDAP, however the release 2.4.xx comes with a slapd.conf.
Can someone please clarify what this file is used for in release 2.4.xx?
Would be greatly appreciated.
Thank you!
