Problem with "force user to password reset at first login
by Rajagopal Rc 30 Oct '23

30 Oct '23

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.

How to enable memberOf overlay with posixGroup?
by MegaBrutal 16 Aug '17

16 Aug '17

Hi all, I've spent days trying to figure out how could I enable the memberOf overlay, and it doesn't seem to be easy for an LDAP-noob. I've read like 50+ tutorials which didn't help me get it working. Use case: I want to have 2 main groups which control access to different services on my network. A "unixusers" which is a minimum to log in to Linux servers (having a hostObject entry for the user is another requirement, which is irrelevant to this question, as I already solved that problem); and a "cloudusers" group which enables log in to my ownCloud instance. The groups should enforce the following rules: – Only users in "cloudusers" should be allowed to log in to ownCloud. – Users in "unixusers" are allowed to log in to a set of Linux servers controlled by "host" (hostObject) entries. – Users not in the "unixusers" group may not log in to any Linux systems, even if they have "host" entries. Problems: – ownCloud complains that the memberOf overlay is not enabled, hence it doesn't let me restrict access to the "cloudusers" group. It would allow any users regardless of any group memberships, which is not acceptable. – I have a similar problem on Linux with PAM: I can't really get it to consider "unixusers" membership for user logins, although I got the "host" entries working correctly, so at least I can already restrict access with that. My guess is that it all boils down to the lack of memberOf overlay. I also figured that memberOf would need groupOfNames groups, while I need posixGroup type groups. I evaluated the possibility to use groupOfNames, but it lacks the necessary gidNumber attribute which is a requirement for Unix groups. But anyway, I can't enable memberOf even for groupOfNames. I can't enable memberOf by any means. My OpenLDAP uses the new configuration method and it completely ignores slapd.conf, so the config must be injected with ldapadd to cn=config. Could you please help me with this? Regards, MegaBrutal

[Q] "selective" ACL
by Zeus Panchenko 26 Jul '17

26 Jul '17

hi, I'm trying to configure a not complex (as I believe) ACL ... but have some difficulties I have two posixGroup groups cn=admins,ou=group,dc=foo cn=coadmins,ou=group,dc=foo my users resides in ou=People,dc=foo so, in subtree ou=People,dc=foo I need to allow anything to admins (and it is not difficult of course) for example this works for me: access to dn.subtree="ou=People,dc=foo" by set="[cn=admin,ou=group,dc=foo]/memberUid & user/uid" manage by self write by users read by * break but in addition I need to allow my coadmins to do the same things except manipulations upon the objects which belong to admins ( ...anyobject,uid=adminuser,ou=People,dc=foo ) so, the question is: how? (if it is possible at all) :( please, advise -- Zeus V. Panchenko jid:zeus@im.ibs.dn.ua IT Dpt., I.B.S. LLC GMT+2 (EET)

Your slapd.conf has no rootdn configured. You need to configure it if you want ppolicy to function correctly.

Re: memberOf overlay issues with 2.4.44 + ITS 8432 patch

Ok good to know! The issue I created occurred when deleting the group, which I believe is the original complaint in the ITS as well. So I will add individual membership deletes as a part of that test too. --Quanah > On Dec 30, 2016, at 9:31 PM, Paul B.

Thanks much... Well, it seems to be some sort of race condition. I've only had it occur one time out of some 700+ attempts. I don't think it is really related to 4-way MMR at all, but it may be the larger the number of consumers of the accesslog, the more likely it is to occur (so you'll see it more often in 4-way MMR). I did want to confirm that you see this on servers that are long running (I.e., they've been running for a long time, and had other group deletes that went through w/o issue during that time). If so, then I can modify the test to randomly add and delete groups as a part of the test, increasing the likelyhood of triggering the issue within the test.

Doesn't ring a bell, and unfortunately it looks like your binaries are stripped, so the backtrace doesn't contain useful information. :( --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>
