RolesSearch in AdvancedLdapLoginModule is doing a needless LDAP call for each individual role --------------------------------------------------------------------------------------------- Key: SECURITY-934 URL: https://issues.jboss.org/browse/SECURITY-934 Project: PicketBox Issue Type: Bug Components: Negotiation 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 https://issues.jboss.org/browse/SECURITY-891 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}|
