LDAP Attribute Resolution
The following configuration describes how to fetch and retrieve attributes from LDAP attribute repositories.
The following settings and properties are available from the CAS configuration catalog:
cas.authn.attribute-repository.ldap[0].base-dn=
Base DN to use.
There may be scenarios where different parts of a single LDAP tree could be considered as base-dns. Rather than duplicating
the LDAP configuration block for each individual base-dn, each entry can be specified
and joined together using a special delimiter character. The user DN is retrieved using the combination of all base-dn and DN
resolvers in the order defined. DN resolution should fail if multiple DNs are found. Otherwise the first DN found is returned.
Usual syntax is: |
cas.authn.attribute-repository.ldap[0].bind-credential=
The bind credential to use when connecting to LDAP. |
cas.authn.attribute-repository.ldap[0].bind-dn=
The bind DN to use when connecting to LDAP. LDAP connection configuration injected into the LDAP connection pool can be initialized with the following parameters:
|
cas.authn.attribute-repository.ldap[0].ldap-url=
The LDAP url to the server. More than one may be specified, separated by space and/or comma. |

cas.authn.attribute-repository.ldap[0].attributes=
Map of attributes to fetch from the source. Attributes are defined using a key-value structure where CAS allows the attribute name/key to be renamed virtually to a different attribute. The key is the attribute fetched from the data source and the value is the attribute name CAS should use for virtual renames. Attributes may be allowed to be virtually renamed and remapped. The key in the attribute map is the original attribute, and the value should be the virtually-renamed attribute. To fetch and resolve attributes that carry tags/options, consider tagging the mapped attribute as such:affiliation=affiliation .

cas.authn.attribute-repository.ldap[0].block-wait-time=PT3S
