[Maria-discuss] pam authentication not working after few hours

Hi everyone, I have problems with mariadb 10.3.15 in a centos 7 environment. I configured mariadb to authenticate users via pam module while the system is a member of an active directory domain. Everything works fine except that authentication process stops working after few hours. Please note that only users authenticated via pam are facing this issue. Local users keep authenticating... The moment I restart mariadb service everything works fine again. Would you please confirm whether this issue is somewhat related with others I read will be fixed in next release (10.3.16) or not? Thank you, Fabrizio
