Salut @Reheer,
From Jitsi, Authentication against local AD server not working.
I have no AD but only plain LDAP,
From: Portainer → Containers → jitsi_prosody_1 → Console:
root@d6878aab57cb:/# apt-get update
root@d6878aab57cb:/# apt-get install ldap-utils
root@d6878aab57cb:/# ldapsearch -H ldaps://toto-dev.org:636 -x -D cn=ldapservice,dc=directory,dc=nh -w ABCDEF1234567890 -b dc=directory,dc=nh
...
# michelandre, People, directory.nh
dn: uid=michelandre,ou=People,dc=directory,dc=nh
uidNumber: 1001
gidNumber: 1000
uid: michelandre
...
root@d6878aab57cb:/#
I modified /opt/jitsi/.env
ENABLE_GUESTS=0
ENABLE_AUTH=1
AUTH_TYPE=ldap
ENABLE_WELCOME_PAGE=1
AUTH_TYPE=ldap
LDAP_URL=ldaps://toto-dev.org:636
LDAP_BASE=dc=directory,dc=nh
LDAP_BINDDN=cn=ldapservice,dc=directory,dc=nh
LDAP_BINDPW=ABCDEF1234567890
LDAP_FILTER=(uid=%u)
LDAP_AUTH_METHOD=bind
LDAP_USE_TLS=1
I then relaunched docker-compose:
# cd /opt/jitsi ; docker-compose down && rm -rf .jitsi-meet-cfg/ ; docker-compose up -d
THEN THE MIRACLE HAPPENS

Thank you so much for that tip on making aqua persistent and mainly for the one to install ldapsearch with apt-get install ldap-utils. The latter allowed me to confirm, unlike Portainer, that prosody could connect to LOCAL LDAP.
Two posts and two problems resolved, I put you on my list of The Greatests.
You didn’t make my day, but my full month…

P.S. I think that Portainer has a bug for testing the connection to LDAP ???
