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

dynlist vs memberof performance issues
by Mark Cairney
Hi,
I've been out the LDAP loop for a bit but the recent discussion of the
memberof overlay on 2.5 piqued my curiosity. Having upgraded a Dev box,
removed the memberof elements from the database and replaced the
memberof overlay with dynlist the queries appear to work as expected but
are both a) slow and b) heavily CPU-intensive on the LDAP server.

I'm guessing that as the values are computed that this will be heavier
on the CPU but it seems a bit excessive? Has anyone else noticed any
similar performance issues?
This is a relatively low-specced DEV server (2 vCPUs, 4GB RAM) so I
guess this could be a factor but there's no io waiting on the server and
no swapping?
The database is on a par in size with our Production service ( about
400K user objects with 1 group object per user and then about 80K actual
groups of users)

slow memberOf queries in 2.5 with dynlist overlay
by Paul B. Henson
I'm still trying to figure out why my servers sometimes get into a state
where queries requesting the memberOf attribute take an exceedingly long
time to process, for example:
Feb 13 19:46:05 ldap-02 slapd[13564]: conn=297643 fd=104 ACCEPT from PATH=/var/symas/run/ldapi (PATH=/var/symas/run/ldapi)

Feb 13 19:46:05 ldap-02 slapd[13564]: conn=297643 op=1 SRCH attr=memberOf

How is the qtime calculated? It is nice and short, despite the wall clock
reading over 30 seconds :(.
Usually I have to reboot the server completely to clear this up, but this
time I just had to restart it, and then the queries were lickity split
again:
Feb 13 19:55:01 ldap-02 slapd[89655]: conn=1556 fd=40 ACCEPT from PATH=/var/symas/run/ldapi (PATH=/var/symas/run/ldapi)

Over 30 seconds elapsed time to .2 seconds? I'd like to see the .2 all
the time :).
When the server gets like this, there's a very high read IO load, 200-300Mb/s,
compared to generally less than 1Mb/s when things are working right.
It almost seems like it's doing a full disk scan searching for members
every time.
Any suggestions on what to dig into?
Thanks...

STARTTLS vs LDAPS
by thomaswilliampritchard＠gmail.com
At risk of beating a dead horse, I'd like to hear considerations on STARTTLS vs LDAPS. I'm also particularly interested if openldap plans to support LDAPS long term or if there's actually a deprecation effort going on around LDAPS where it would one day no longer be supported by openldap.
This seems to be the most comprehensive post discussing the virtue of the two. https://security.stackexchange.com/questions/257749/is-ldaps-or-starttls-...
I also found a post in this Archive from 2018 that seems to indicate a change of opinion where LDAPS should be preferred, and not deprecated.
https://lists.openldap.org/hyperkitty/list/openldap-technical@openldap.or...
Does openldap agree that LDAPS should now be the preferred implementation and STARTLS should be discouraged?
I do not have a security background and there is certainly a lot of room for me to misunderstand, but it seems like STARTTLS leaves the door open for a "tls downgrade attack" where a man in the middle could essentially reply to a client effectively saying start tls is not supported and then the client falls back to non tls communication (which is obviously unfortunate). Even if the backend server is properly not responding to clients until STARTTLS is initiated, the man in the middle could initiate a connection with STARTTLS to the ldap server and be talking plaintext to the client. Is that legitimately possible or am I missing a nuance? If one were to only support clients over LDAPS it seems this would be mitigated?
Thanks for the considerations, looking forward to hearing the expert opinions on the topic.

delete glue entry
by Michael Ströder
HI!
Had a MDB database with a glue entry in it on all replicas in a
multi-provider setup (release 2.6.1). I could not update this entry anymore.
Is it possible to delete a glue entry via LDAP? All subordinate entries
were already removed before.
Ciao, Michael.

Deny write access to new accounts
by beren beren
Hi.
Is it possible to make admin Bob unable to edit accounts (delete, create,
change passwords)created this year ? There is an idea to move them to a
group or OU and give Bob the rights to write only there. Is there a more
elegant solution ?
