Package org.jivesoftware.openfire.ldap

Class LdapManager

java.lang.Object
org.jivesoftware.openfire.ldap.LdapManager
public class LdapManager extends Object
Centralized administration of LDAP connections. The getInstance() method should be used to get an instance. The following properties configure this manager:
  • ldap.host
  • ldap.port
  • ldap.baseDN
  • ldap.alternateBaseDN
  • ldap.adminDN
  • ldap.adminPassword
  • ldap.usernameField -- default value is "uid".
  • ldap.usernameSuffix -- default value is "".
  • ldap.nameField -- default value is "cn".
  • ldap.emailField -- default value is "mail".
  • ldap.searchFilter -- the filter used to load the list of users. When defined, it will be used with the default filter, which is "([usernameField]={0})" where [usernameField] is the value of ldap.usernameField.
  • ldap.groupNameField
  • ldap.groupMemberField
  • ldap.groupDescriptionField
  • ldap.posixMode
  • ldap.groupSearchFilter
  • ldap.flattenNestedGroups
  • ldap.debugEnabled
  • ldap.sslEnabled
  • ldap.startTlsEnabled
  • ldap.autoFollowReferrals
  • ldap.autoFollowAliasReferrals
  • ldap.initialContextFactory -- if this value is not specified, "com.sun.jndi.ldap.LdapCtxFactory" will be used.
  • ldap.connectionPoolEnabled -- true if an LDAP connection pool should be used. False if not set.
  • ldap.findUsersFromGroupsEnabled
    • -- If true then Openfire users will be identified from the members of Openfire groups instead of from the list of all users in LDAP. This option is only useful if you wish to restrict the users of Openfire to those in certain groups. Normally this is done by applying an appropriate ldap.searchFilter, but there are a number of reasons why you may wish to enable this option instead:
    • If group members cannot be identified by the attributes of the user in LDAP (typically the memberOf attribute) then users cannot be filtered using ldap.searchFilter
    • If the number of Openfire users is small compared to the total number of users in LDAP then it may be more performant to identify these users from the groups to which they belong instead of applying an ldap.searchFilter. Note that if this is not the case, enabling this option may significantly decrease performance.
    In any case, an appropriate ldap.groupSearchFilter should be applied to prevent LDAP users belonging to any group being selected as Openfire users. (default value: false)

      public boolean isFindUsersFromGroupsEnabled()

    • createNewAbsolute

      public static LdapName createNewAbsolute(LdapName base, Rdn[] relative)

    • findUserRDN

      public Rdn[] findUserRDN(String username) throws Exception
      Finds a user's RDN using their username. Normally, this search will be performed using the field "uid", but this can be changed by setting the usernameField property.

      Searches are performed over all subtrees relative to the baseDN. If the search fails in the baseDN then another search will be performed in the alternateBaseDN. For example, if the baseDN is "o=jivesoftware, o=com" and we do a search for "mtucker", then we might find a userDN of "uid=mtucker,ou=People". This kind of searching is a good thing since it doesn't make the assumption that all user records are stored in a flat structure. However, it does add the requirement that "uid" field (or the other field specified) must be unique over the entire subtree from the baseDN. For example, it's entirely possible to create two dn's in your LDAP directory with the same uid: "uid=mtucker,ou=People" and "uid=mtucker,ou=Administrators". In such a case, it's not possible to uniquely identify a user, so this method will throw an error.

      The dn that's returned is relative to the default baseDN.

      Parameters:
      username - the username to lookup the dn for.
      Returns:
      the dn associated with username.
      Throws:
      Exception - if the search for the dn fails.

    • findUserRDN

      public Rdn[] findUserRDN(String username, LdapName baseDN) throws Exception
      Finds a user's RDN using their username in the specified baseDN. Normally, this search will be performed using the field "uid", but this can be changed by setting the usernameField property. Searches are performed over all sub-trees relative to the baseDN unless sub-tree searching has been disabled. For example, if the baseDN is "o=jivesoftware, o=com" and we do a search for "mtucker", then we might find a userDN of "uid=mtucker,ou=People". This kind of searching is a good thing since it doesn't make the assumption that all user records are stored in a flat structure. However, it does add the requirement that "uid" field (or the other field specified) must be unique over the entire subtree from the baseDN. For example, it's entirely possible to create two dn's in your LDAP directory with the same uid: "uid=mtucker,ou=People" and "uid=mtucker,ou=Administrators". In such a case, it's not possible to uniquely identify a user, so this method will throw an error.

      The RDN that's returned is relative to the baseDN.

      Parameters:
      username - the username to lookup the dn for.
      baseDN - the base DN to use for this search.
      Returns:
      the RDN associated with username.
      Throws:
      Exception - if the search for the RDN fails.

    • findGroupRDN

      public Rdn[] findGroupRDN(String groupname) throws Exception
      Finds a groups's RDN using it's group name. Normally, this search will be performed using the field "cn", but this can be changed by setting the groupNameField property.

      Searches are performed over all subtrees relative to the baseDN. If the search fails in the baseDN then another search will be performed in the alternateBaseDN. For example, if the baseDN is "o=jivesoftware, o=com" and we do a search for "managers", then we might find a groupDN of "uid=managers,ou=Groups". This kind of searching is a good thing since it doesn't make the assumption that all user records are stored in a flat structure. However, it does add the requirement that "cn" field (or the other field specified) must be unique over the entire subtree from the baseDN. For example, it's entirely possible to create two dn's in your LDAP directory with the same cn: "cn=managers,ou=Financial" and "cn=managers,ou=Engineers". In such a case, it's not possible to uniquely identify a group, so this method will throw an error.

      The RDN that's returned is relative to the default baseDN.

      Parameters:
      groupname - the groupname to lookup the RDN for.
      Returns:
      the RDN associated with groupname.
      Throws:
      Exception - if the search for the RDN fails.

    • findGroupAbsoluteDN

    • findGroupRDN

      public Rdn[] findGroupRDN(String groupname, LdapName baseDN) throws Exception
      Finds a groups's dn using it's group name. Normally, this search will be performed using the field "cn", but this can be changed by setting the groupNameField property.

      Searches are performed over all subtrees relative to the baseDN. If the search fails in the baseDN then another search will be performed in the alternateBaseDN. For example, if the baseDN is "o=jivesoftware, o=com" and we do a search for "managers", then we might find a groupDN of "uid=managers,ou=Groups". This kind of searching is a good thing since it doesn't make the assumption that all user records are stored in a flat structure.

    • retrieveList

      public List<String> retrieveList(String attribute, String searchFilter, int startIndex, int numResults, String suffixToTrim)
      Generic routine for retrieving a list of results from the LDAP server. It's meant to be very flexible so that just about any query for a list of results can make use of it without having to reimplement their own calls to LDAP. This routine also accounts for sorting settings, paging settings, any other global settings, and alternate DNs. The passed in filter string needs to be pre-prepared! In other words, nothing will be changed in the string before it is used as a string.
      Parameters:
      attribute - LDAP attribute to be pulled from each result and placed in the return results. Typically pulled from this manager.
      searchFilter - Filter to use to perform the search. Typically pulled from this manager.
      startIndex - Number/index of first result to include in results. (-1 for no limit)
      numResults - Number of results to include. (-1 for no limit)
      suffixToTrim - An arbitrary string to trim from the end of every attribute returned. null to disable.
      Returns:
      A simple list of strings (that should be sorted) of the results.

    • sanitizeSearchFilter

      public static String sanitizeSearchFilter(String value)
      Escapes any special chars (RFC 4515) from a string representing a search filter assertion value.
      Parameters:
      value - The input string.
      Returns:
      A assertion value string ready for insertion into a search filter string.

    • escapeForJNDI

      public static LdapName escapeForJNDI(Rdn... rdn)
      Returns a JNDI Name for an array of RDNs that is suitable to use to access LDAP through JNDI. This method applies JDNI-suitable escaping to each RDN
      When using the JNDI to access an LDAP service, you should be aware that the forward slash character ("/") in a string name has special meaning to the JNDI. If the LDAP entry's name contains this character, then you need to escape it (using the backslash character ("\")). For example, an LDAP entry with the name "cn=O/R" must be presented as the string "cn=O\\/R" to the JNDI context methods.
      Parameters:
      rdn - The names to escape (cannot be null).
      Returns:
      A JNDI name representation of the values (never null).

      Parameters:
      value - The input string.
      acceptWildcard - true to accept wildcards, otherwise false
      Returns:
      A assertion value string ready for insertion into a search filter string.
