If I understand things correctly... The server does not hash the password. The server never gets to see the plaintext password.

Hi to all, I just installed a fresh 2.5 server with the symas-packages and debian 11. I can start the service, but as soon as I try to authenticate for example with: ldapsearch -x -D cn=admin,dc=example,dc=net -W the server crashes, I put the loglevel to "any" and I saw kernel: traps: slapd[18020] trap invalid opcode ip:7febaf26a415 sp:7fc3ad4b69e0 error:0 in libargon2.so.1[7febaf266000+5000] Everytime I try to authenitcate. All packages are up to date. any idea

If the other moduleload in there is back_mdb.la, should I also go with ppolicy.la or should I stick with .so?

RoleOccupant filter
by forumforeign 09 Mar '23

09 Mar '23

Hello. I have LDAP groups which keep users inside. Here an example of group: # developer, roles, domain.com dn: cn=developer,ou=roles,dc=domain,dc=com objectClass: organizationalRole cn: developer roleOccupant: uid=user1,ou=people,dc=domain,dc=com roleOccupant: uid=user2,ou=people,dc=domain,dc=com I need to make a search filter, which can say, if certain user belong to group? Or does certain group have a user? Next filter give all uids of group developer: openldapsearch -v -H ldaps://<ldap_host> -x -b 'dc=domain,dc=com' -W -D "cn=vmail,ou=services,dc=domain,dc=com" '(&(objectClass=organizationalRole)(cn=developer))' RoleOccupant When I try to add 'uid' to filter it doesn't return any records: '(&(objectClass=organizationalRole)(cn=developer)(uid=user1,ou=people,dc=domain,dc=com))' RoleOccupant '(&(objectClass=organizationalRole)(cn=developer)(uid=user1,ou=people,dc=domain,dc=com))' '(&(objectClass=organizationalRole)(cn=developer)(uid=user1*))' RoleOccupant How I can change filter, that check if user1 belong to group developer?

I'm responsible for the Master LDAP-Server, but there are a few ro-replicas in other departments where I'm not responsible - and I have no access. Is it possible to migrate the master server to the new version and update the replicas (running 2.4.59) later, independent from the master (migration)? Are there any problems to be expected? Regards and many thanks Meike
