Summary: RFE: More metrics in cn=monitor

Currently I'm grepping metrics from syslog with mtail:
https://gitlab.com/ae-dir/ansible-ae-dir-server/-/blob/master/templates/mta…
With a new binary logging this is not possible anymore.
Thus it would be nice if cn=monitor provides more metrics.
1. Overall connection count per listener starting at 0 when started. This would
be a simple counter added to:
entries cn=Listener 0,cn=Listeners,cn=Monitor
2. Counter for the various "deferring" messages separated by the reason for
deferring.
3. Counters for all possible result codes. In my mtail program I also label it
with the result type.

Summary: Crash on exit with OpenSSL 3

A program using libldap will crash on exit after using SSL connection.
How to reproduce on CentOS 9:
Uncomment the following lines in /etc/pki/tls/openssl.cnf:
[provider_sect]
legacy = legacy_sect
[legacy_sect]
activate = 1
Run the command (you must enter a valid LDAP server address):
python3 -c "import ldap; ldap.initialize('ldaps://<LDAP SERVER
ADDRESS>').whoami_s()"
Another example (no server required):
python3 -c "import ctypes;
ctypes.CDLL('libldap.so.2').ldap_pvt_tls_init_def_ctx(0)"
Results:
Segmentation fault (core dumped)
Backtrace from gdb:

The problem is that ldap_int_tls_destroy() is called after the clean up of
libssl.
On program exit, at first default_context_int is cleaned up (OPENSSL_cleanup()
was registered with atexit()):
0 ossl_lib_ctx_default_deinit () at crypto/context.c:196
1 OPENSSL_cleanup () at crypto/init.c:424
2 OPENSSL_cleanup () at crypto/init.c:338

Then ossl_lib_ctx_get_data() tries to use default_context_int.lock, which is
NULL. ldap_int_tls_destroy() is called by ldap_int_destroy_global_options(),
registered by "__attribute__ ((destructor))".
It seems that shared library destructors are always called before functions
registered with atexit().
A solution may be to modify libraries/libldap/init.c to use atexit() instead of
"__attribute__ ((destructor))". atexit() manual page says: "Since glibc 2.2.3,
atexit() can be used within a shared library to establish functions that are
called when the shared library is unloaded.".
Functions registered with atexit() are called in the reverse order of their
registration, so libssl must by initialized before libldap. If the order is
wrong, libldap should detect it somehow and exit with abort().

Summary: Deprecate GnuTLS support

Severity: normal
Priority: ---
Component: libraries
Assignee: bugs(a)openldap.org

Target Milestone: ---
Support for GnuTLS was added specifically for the Debian (and thus Ubuntu) due
to the license objections at the time that the Debian project had for the
OpenSSL license.
Since that time, Debian has reclassified OpenSSL as a core library and the
OpenSSL project has resolved the original complaint by licensing OpenSSL 3 and
later under the Apache License v2.
Thus there is no longer a reason to maintain support for GnuTLS and given the
long standing concerns over the security and quality of the GnuTLS bridge in
addition to the extra cost of maintaining that code, it should be marked as
deprecated and removed in a future release.

Hi,
This is a feature request.
I would like to be able to chooses between Argon2i, Argon2d and Argon2id in
slappasswd like in argon2 command:
# argon2
Usage: argon2 [-h] salt [-i|-d|-id] [-t iterations] [-m log2(memory in KiB) |
-k memory in KiB] [-p parallelism] [-l hash length] [-e|-r] [-v (10|13)]
Password is read from stdin
Parameters:
salt The salt to use, at least 8 characters
-i Use Argon2i (this is the default)
-d Use Argon2d instead of Argon2i
-id Use Argon2id instead of Argon2i
-t N Sets the number of iterations to N (default = 3)
-m N Sets the memory usage of 2^N KiB (default 12)
-k N Sets the memory usage of N KiB (default 4096)
-p N Sets parallelism to N threads (default 1)
-l N Sets hash output length to N bytes (default 32)
-e Output only encoded hash
-r Output only the raw bytes of the hash
-v (10|13) Argon2 version (defaults to the most recent version,
currently 13)
-h Print argon2 usage
Example:
/usr/local/etc/openldap # /usr/sbin/slappasswd -h "{ARGON2}" -o
module-load="argon2.so i" -s secret
/usr/local/etc/openldap # /usr/sbin/slappasswd -h "{ARGON2}" -o
module-load="argon2.so d" -s secret
/usr/local/etc/openldap # /usr/sbin/slappasswd -h "{ARGON2}" -o
module-load="argon2.so id" -s secret

Playing with the DB provided in ITS#10041 on master, interrupting the
ldapsearch sometimes leads to a slapd crash. It's not 100% repeatable and the
debugger shows dynlist_search2resp touching memory freed by
dynlist_search_cleanup already, which doesn't make sense. Might be something
else is happening at the same time.

Summary: dynlist's @groupOfUniqueNames is considered only for
the first configuration line
Product: OpenLDAP
Version: 2.5.13
Hardware: x86_64
OS: Linux
Status: UNCONFIRMED
Keywords: needs_review
Severity: normal

Component: overlays

Reporter: msl(a)touk.pl
Target Milestone: ---
If we consider the following configuration of dynlist:
{0}toukPerson labeledURI uniqueMember+memberOf@groupOfUniqueNames
{1}groupOfURLs memberURL uniqueMember+dgMemberOf@groupOfUniqueNames
The {0} entry will correctly populate the memberOf relatively to static group
membership.
The {1} entry will produce dgMemberOf with dynamic group membership correctly
(based on memberURL query) but it will not populate static entries IF {0} entry
in configuration is present. IF I remove {0} from the dynlist configuration -
or - remove @groupOfUniqueNames part from this configuration line, then both
dynamic and static entries will be populated correctly for {1}.
So the effects are as follows on some user entry:
if both {0} and {1} are present - {1} produced only dynamic groups:
memberOf: cn=adm,ou=touk,ou=group,dc=touk,dc=pl
memberOf: cn=touk,ou=touk,ou=group,dc=touk,dc=pl
dgMemberOf: cn=dyntouk,ou=dyntest,ou=group,dc=touk,dc=pl
if both {0} and {1} are present and @groupOfUniqueNames is removed from {0} -
{1} produced static+dynamic groups:
dgMemberOf: cn=adm,ou=touk,ou=group,dc=touk,dc=pl
dgMemberOf: cn=touk,ou=touk,ou=group,dc=touk,dc=pl
dgMemberOf: cn=dyntouk,ou=dyntest,ou=group,dc=touk,dc=pl
If only {1} is present - {1} produced static+dynamic groups:
dgMemberOf: cn=adm,ou=touk,ou=group,dc=touk,dc=pl
dgMemberOf: cn=touk,ou=touk,ou=group,dc=touk,dc=pl
dgMemberOf: cn=dyntouk,ou=dyntest,ou=group,dc=touk,dc=pl
For completness - if only {0} is present:
memberOf: cn=adm,ou=touk,ou=group,dc=touk,dc=pl
memberOf: cn=touk,ou=touk,ou=group,dc=touk,dc=pl
I would expect this behavior to be correct for the first case - {0} and {1}.
memberOf: cn=adm,ou=touk,ou=group,dc=touk,dc=pl
memberOf: cn=touk,ou=touk,ou=group,dc=touk,dc=pl
dgMemberOf: cn=dyntouk,ou=dyntest,ou=group,dc=touk,dc=pl
dgMemberOf: cn=adm,ou=touk,ou=group,dc=touk,dc=pl
dgMemberOf: cn=touk,ou=touk,ou=group,dc=touk,dc=pl
