Error description

  • PI97974 was about LDAP Search filter issue, which did not
    handle parenthesis correctly.
     LdapRegistryI 3
    CN=xxxxx\(rtp\),CN=Users,dc=wasl3sec2,dc=raleigh,dc=ibm,dc=com:
    [LDAP: error code 34 - 0000208F: LdapErr: DSID-0C090787,
    comment: rror processing name, data 0, v1db1
    -----
    After upgrading from version 9.0.0.7 to 9.0.0.10, user searches
    fail in both the administrative console and the systems,
    apparently by the character parentheses '(' ')' -  \(xyz1\) in
    the DN of the entries in the LDAP directory. With the rollback
    to FP 7 the authentication works again.
    Exception stack
     LdapRegistryI E  SECJ0352E: Could not get the users matching
    the pattern cn=my UserName  \(xyz1\),ou=Users,o=IBM,o=com
    because of the following exception
    javax.naming.InvalidNameException: cn=my UserName
    \(xyz1\),ou=Users,o=IBM,o=com: [LDAP: error code 34 - Invalid
    DN Syntax]; remaining name 'cn=my UserName

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server                                      *
    ****************************************************************
    * PROBLEM DESCRIPTION: LDAP user search fails when the         *
    *                      user's DN includes parenthesis          *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Due to side effect of PI97974 (included in 9.0.0.10 and
    8.5.5.15), LDAP search for the user whose DN name includes
    parenthesis fails. It is due to unnecessary escape character
    in the DN.
