Parameters

Examples

Example 1

Creates an LDAP URL search string for the LDAP SunONE Directory Server.

sp_ldapadmin set_primary_url,'ldap://voyager:389/
    ou=People,dc=MyCompany,dc=com??sub?uid=*'

The search string identifies a directory server listening on host name “voyager,” port number 389 (the default LDAP protocol port), the base node to begin the search is within organizational unit (ou) “People,” and the domain is “MyCompany.com.” It returns all attributes that match the filter uid=*. Adaptive Server replaces the wildcard with the Adaptive Server login name that is to be authenticated.

Example 2

Creates an LDAP URL search string defined in OpenLDAP 2.0.25 using the criteria described in Example 1.

sp_ldapadmin set_primary_url,'ldap://voyager:389/
    dc=MyCompany,dc=com??sub?cn=*'

Example 3

Sets the secondary LDAP URL search string to null, indicating no failover and no secondary LDAP server.

sp_ldapadmin set_secondary_url, null

Example 4

Creates an LDAP URL search string with a compound filrer.

sp_ldapadmin set_primary_url, 'ldap://voyager:389/
    ou=people,dc=siroe,dc=com??sub?(&(uid=*)
    (ou=accounting))

Example 5

Uses the default Microsoft Active Directory schema found on Windows 2000 controllers:

1> sp_ldapadmin set_access_acct, 'cn=aseadmin, cn=Users, dc=mycompany, 
      dc=com', 'aseadmin secret password'
2> go

1> sp_ldapadmin set_dn_lookup_url,
    'ldap://mydomainhostname:389/cn=Users,dc=mycompany,dc=com?
     distinguishedName?sub?samaccountname=*' 
2> go

1> sp_ldapadmin set_primary_url,'ldap://mydomainhostname:389/'
2> go

The “aseadmin” username is added to the Active Directory server and granted read access to the trees and objects where users are found. The LDAP attribute specified by distinguishedName is obtained and used to authenticate the user. The filter specifies a search on attribute samaccountname=*; the * wildcard is replaced with the name from the Adaptive Server login record.

For example, “samaccountname=jqpublic” returns DN attribute “distinguishedName” with value “cn=John Q. Public, cn=Users,dc=mycompany, dc=com” to Adaptive Server. Adaptive Server uses this string to bind to ldap://mydomainhostname:389. If the bind is successful, authentication succeeds.

Example 6

Sets the maximum number of native threads to 12:

sp_ldapadmin 'set_max_ldapua_native_threads', '12'

Example 7

sets the time that Adaptive Server waits for a response from the LDAP server before abandoning the authentication request to 25,000 milliseconds:

sp_ldapadmin, 'set_timeout', '25000'

Example 8

Disables the authentications requests until the LDAP descriptor can accept new authentication requests:

sp_ldapadmin 'set_abandon_ldapua_when_full', 'false'

Example 9

Displays the current LDAP values:

sp_ldapadminPrimary:
URL:                  'ldap://linuxpuneeng1:50917/'
DN Lookup URL:
'ldap://linuxpuneeng1:50917/dc=sybase,dc=com??sub?uid=*'
Access Account:      'cn=Directory Manager'
Active:              'TRUE'
Status:              'READY'
Secondary:
URL:                 ''
DN Lookup URL:       ''
Access Account:      ''
Active:              'FALSE'
Status:              'NOT SET'
Timeout value:       '5000' milliseconds
Log interval:        '1' minutes
Number of retries:   '3'
Maximum LDAPUA native threads per Engine: '400'
Maximum LDAPUA descriptors per Engine: '3'
Abandon LDAP user authentication when full: 'false'(return status = 0)

Usage

• The LDAP vendor determines the syntax of the search string. In all cases, the search string specifies the attribute name that uniquely identifies the user in the form “attribute=wildcard” as in “cn=*.”

• The first attribute in a compound filter must define the Relative Distinguished Name (RDN). For example, “...sub?(uid=*)(ou=group).” Otherwise, the authentication fails.

• When a search string is added, Adaptive Server verifies that it uses valid LDAP URL syntax and that it references an existing node. To ensure that the valid string returns expected values, carefully choose and verify the search string when configuring Adaptive Server.

• The secondary URL search string enables failover to another LDAP server. Adaptive Server uses the primary URL search string unless the LDAP Server is not active or the search string is invalid. In this event, Adaptive Server uses the secondary URL search string for authentication.

• The login sequence of searched DN algorithm requires Adaptive Server to bind to the LDAP server using the access account before it can perform searches. Adaptive Server obtains an LDAP descriptor (handle) as a result of the bind. This descriptor is used for searching the DN of the login on the LDAP server.
