Hynek Švábek created WFLY-6062: ---------------------------------- Summary: RolesSearch in AdvancedLdapLoginModule is doing a needless LDAP call for each individual role Key: WFLY-6062 URL: https://issues.jboss.org/browse/WFLY-6062 Project: WildFly Issue Type: Bug Components: Security Reporter: Hynek Švábek Assignee: Darran Lofthouse There will be needless LDAP calls if we use AdvancedLdap login module. If a user is a member of (lets say) 100 groups, then we can get an extra 100 calls to the LDAP server. It can be performance problem. Same problem was in LdapExt login module.
