[Qlustar General] Password sync for ldap users.

Greetings, I have qluster 12 installed on a small HPC in our university. To create users remotely, I usually use the terminal and .ldif files to create users. I also use the following command to change users passwords from the terminal: ldappasswd -Z -D "cn=admin,dc=gavazang,dc=qlustar" -W -S "cn= saeed,ou=users,dc=gavazang,dc=qlustar" This works and the password is changed. However, the problem is that once in a while the user cant connect to the cluster and I have to reset the password again and again and this happens frequently. Should I do anything to sync the passwords after changing them? Or am I doing something wrong here? thanks in advance for your assistance
