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)

Delta-sync replication: is it possible to force resync delta?
by skeletor
Hi.
I use delta-sync replication on version 2.4. Sometimes, some records
don't send to slave. Insofar as this is delta-sync after a new update
slave receive only last update. Therefore slave and master are not
consistent. Is it possible run force resync from accesslog to consistent
check if all records are present on slave?
May be this is a bug on version 2.4 and it already has been fixed in
newer version?
master 2.4.57
slave 2.4.55

2.6 MMR 4-way with one master different flavor of linux
by Dave Macias
Hello,
Hope everyone is doing well.
Our current environment:
3-way MMR (syncrepl) with centos 7 using v2.6
We want to add a 4th master but with Rocky Linux 8.
Why rocky? because eventually we will migrate the 3 masters to rocky linux too. But that will take some time…
Any concerns with mixing linux flavor but using same openldap version?
Dont do it?
Any input is appreciated.
Thank you,
Dave

[LMDB] mdb_env_set_mapsize and read transactions
by Ken Wenzel
Hello,
I like to implement an autogrow functionality for LMDB.
The documentation for mdb_env_set_mapsize says that no transactions should
be active when using this function.
When looking at the code I can see that the function only checks if there is
an active WRITE transaction and in this case it returns an error.
Is it possible to reuse existing READ transactions or even associated
cursors after mdb_env_set_mapsize has been called?
Thank you and best regards,
Ken

Minor typo in slapo-ppolicy
by Ulrich Windl
Hi!
I just discovered a minor typo in my version of the slapo-ppolicy manual page (possibly it's fixed alrerady):
The manual page lists "pwdGraceAuthnLimit", but the attribute returned by slapcat is "pwdGraceAuthNLimit" (different case for 'N')
The name from the schema also is "pwdGraceAuthNLimit".

Question regarding password dictionary rule in OpenLDAP
by Alan Andrea
I have a question regarding password rules that are enforced when a user changes their password in OpenLDAP. We have a need to implement a dictionary rule whereby words and phrases in a dictionary are not allowed in a users password. I am not able to see currently where such functionality exists in OpenLDAP and am wondering if there are any extensions to OPenLDAP that were developed to support this or if it would be required to write code to support this feature?
Thanks,Alan

Need to define behaviour when storing pwdChangedTime
by David Coutadeur
Hi,
When doing a backup / restore on my OpenLDAP 2.5.9 instance, I faced a
behaviour that I think must be defined explicitely, in
draft-behera-ldap-password-policy, or at least in OpenLDAP documentation.
My backup contains an entry like this:
dn: uid=test,ou=people,ou=branch,dc=example,dc=com
cn: test
sn: test
givenName: test
uid: test
userPassword: secret
pwdChangedTime: 20220110153431Z
mail: test(a)domain.com
objectClass: inetOrgPerson
objectClass: organizationalPerson
objectClass: person
There is also a valid default password policy: (which must be defined
before the users in the backup file)
dn: cn=default,ou=ppolicies,dc=example,dc=com
objectClass: pwdPolicy
objectClass: pwdPolicyChecker
objectClass: organizationalRole
cn: default
pwdMaxAge: 7776000
pwdAttribute: userPassword
pwdCheckQuality: 2
pwdLockout: TRUE
pwdMaxFailure: 5
pwdMinLength: 6
pwdMustChange: TRUE
pwdCheckModule: /usr/local/openldap/lib64/ppm.so
When restoring the backup with this command:
ldapadd -x -h '127.0.0.1:389' -D 'cn=Manager,dc=example,dc=com' -w
'secret' -f backup.ldif -e relax
I have an error showing that the attribute pwdChangedTime is duplicated
and must not be defined twice.
I assume that the password policy does not replace my pwdChangedTime
value with the current date, but duplicates the attribute.
Could you define this behaviour somewhere?
1/ Is it possible to update the pwdChangedTime attribute along with the
userPassword ?
2/ If so, what value should be stored? (the given value or the current
date?)
3/ Optionally, update OpenLDAP code according to the defined behaviour
Thanks in advance for your answer.

How to properly test whether an asynchronous ldap_connect() has fully connected?
by nickpelling＠nickpelling.com
I'm trying to run OpenLDAP on a Cortex-M7 processor, but to be a "good citizen" my LDAP client code needs to connect asynchronously. (The code connects synchronously fine.)
Stripped down to the bare minimum (i.e. no error handling) for clarity here (the actual code has tons of error handling), my asynchronous connection code looks like this:
ldap_set_option(pstContext->ld, LDAP_OPT_CONNECT_ASYNC, LDAP_OPT_ON); // Enable async connection
ldap_connect(ld); // Do the LDAP connection
As you'd expect, the next step is to test (asynchronously) whether the connection has completed, but it can't see any OpenLDAP functionality to do this directly.
So here's what my test currently looks like:
/**
* Determine whether a connection has yet connected
*
* @param[in] LDAP connection instance to test
*
* @retval 0 if connection has connected
* @retval -2 if connection is still waiting
* @return ...otherwise an unexpected problem was encountered
*/
int ldap_connection_connected(LDAP * ld)
{
ber_socket_t sd;
int iRetVal;
iRetVal = -99; // Default to "an unexpected problem was encountered"
if (ld->ld_defconn != NULL)
{
if (ld->ld_defconn->lconn_status == LDAP_CONNST_CONNECTED)
{
iRetVal = 0; // i.e. the connection has already connected, so exit early!
}
else
{
// Get the connection's sockbuffer
ber_sockbuf_ctrl( ld->ld_defconn->lconn_sb, LBER_SB_OPT_GET_FD, &sd );
// Check to see if a result has yet been received via this sockbuffer
iRetVal = ldap_int_check_async_open( ld, sd );
}
}
return iRetVal;
}
However, my bind code (i.e. that executes immediately after this) fails to connect to the server after an asynchronous ldap_connect(), even though it works fine after a synchronous ldap_connect(). Moreover, it looks to me (from the timings) as though my test for asynchronous connection is signalling completion earlier than I'm expecting, so I'm wondering if this is not waiting properly, e.g. if it's returning after the very first message response when it should be waiting for a whole series of message responses to arrive.
Am I missing some clever OpenLDAP trick for correctly detecting when asynchronous ldap_connect() calls have fully connected? Thanks!

mdb_txn_begin() before mdb_dbi_open()
by Sam Dave
Hello,
1. I create a read-only transaction on an environment with mdb_txn_begin().
2.Then I get a database handle on the same environment (using mdb_dbi_open() within a separate transaction).
3. Finally I try to create and use a cursor using the database in 2. and transaction in 1. but I get various runtime errors ("Segmentation fault" or "double free or corruption").
However, if I switch 1. and 2., everything works.
Must a database really be created before a transaction? If so, curious to learn if this is mentioned anywhere in the docs (I didn't see it)
Regards,
Sam
