[jboss-jira] [JBoss JIRA] (WFLY-6062) RolesSearch in AdvancedLdapLoginModule is doing a needless LDAP call for each individual role

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. You can see this BZ https://bugzilla.redhat.com/show_bug.cgi?id=1223840 Example from Wireshark for 2 groups: {code} * searchRequest(3) "ou=Roles,ou=AdvancedLdapLoginModuleSpecialNamesTestCasee4b1c459,OU=primary,O=eapqe,DC=JBOSS3,DC=test" wholeSubtree * searchResEntry(3) "CN=JBossAdmin,OU=Roles,OU=AdvancedLdapLoginModuleSpecialNamesTestCasee4b1c459,OU=primary,O=eapqe,DC=JBOSS3,DC=test" | searchResEntry(3) "CN=Slash/Char,OU=Roles,OU=AdvancedLdapLoginModuleSpecialNamesTestCasee4b1c459,OU=primary,O=eapqe,DC=JBOSS3,DC=test" | searchResDone(3) success [2 results] * searchRequest(4) "CN=JBossAdmin,ou=Roles,ou=AdvancedLdapLoginModuleSpecialNamesTestCasee4b1c459,OU=primary,O=eapqe,DC=JBOSS3,DC=test" baseObject * searchResEntry(4) "CN=JBossAdmin,ou=Roles,ou=AdvancedLdapLoginModuleSpecialNamesTestCasee4b1c459,OU=primary,O=eapqe,DC=JBOSS3,DC=test" | searchResDone(4) success [1 result] * searchRequest(5) "CN=Slash/Char,ou=Roles,ou=AdvancedLdapLoginModuleSpecialNamesTestCasee4b1c459,OU=primary,O=eapqe,DC=JBOSS3,DC=test" baseObject * searchResEntry(5) "CN=Slash/Char,ou=Roles,ou=AdvancedLdapLoginModuleSpecialNamesTestCasee4b1c459,OU=primary,O=eapqe,DC=JBOSS3,DC=test" | searchResDone(5) success [1 result] {code}|
