The following authentication modules are included in JBoss EAP 6. Some of these handle authorization as well as authentication. These usually include the word
Role within the Code name.
When you configure these modules, use the
Code value or the full (package qualified) name to refer to the module.
Authentication Modules
| Code | RealmDirect
|
| Class | org.jboss.as.security.RealmDirectLoginModule
|
| Description |
A login module implementation to interface directly with the security realm. This login module allows all interactions with the backing store to be delegated to the realm removing the need for any duplicate and synchronized definitions. Used for remoting calls and management interface.
|
| Option | Type | Default | Description |
|---|---|---|---|
realm |
string
| ApplicationRealm
|
Name of the desired realm.
|
| Code | Client
|
| Class | org.jboss.security.ClientLoginModule
|
| Description |
This login module is designed to establish caller identity and credentials when JBoss EAP 6 is acting as a client. It should never be used as part of a security domain used for server authentication.
|
| Option | Type | Default | Description |
|---|---|---|---|
multi-threaded | true or false
| false
|
Set to true if each thread has its own principal and credential storage. Set to false to indicate that all threads in the VM share the same identity and credential.
|
password-stacking
| useFirstPass or false
| false
|
Set to
useFirstPass to indicate that this login module should look for information stored in the LoginContext to use as the identity. This option can be used when stacking other login modules with this one.
|
restore-login-identity
| true or false
| false
|
Set to true if the identity and credential seen at the start of the
login() method should be restored after the logout() method is invoked.
|
| Code | Remoting
|
| Class | org.jboss.as.security.remoting.RemotingLoginModule
|
| Description |
This login module is used to check if the request currently being authenticated is a request received over a Remoting connection, and if so the identity that was created during the Remoting authentication process is used and associated with the current request. If the request did not arrive over a Remoting connection this module does nothing and allows the JAAS based login to continue to the next module.
|
| Option | Type | Default | Description |
|---|---|---|---|
password-stacking | useFirstPass or false
| false
|
A value of
useFirstPass indicates that this login module should first look to the information stored in the LoginContext for the identity. This option can be used when stacking other login modules with this one.

The authentication happens in 2 steps:
|
| Option | Type | Default | Description |
|---|---|---|---|
baseCtxDN
| fully-qualified DN |
none
|
The fixed DN of the top-level context to begin the user search.

bindCredential
| string, optionally encrypted |
none
|
See Section 16.1.14, “bindCredential Module Option” for details.
|
bindDN
| fully-qualified DN |
none
|
The DN used to bind against the LDAP server for the user and roles queries. This DN needs read and search permissions on the
baseCtxDN and rolesCtxDN values.
|
baseFilter
| LDAP filter string |
none
|
A search filter used to locate the context of the user to authenticate. The input username or
userDN obtained from the login module callback is substituted into the filter anywhere a {0} expression is used. A common example for the search filter is (uid={0}).
|
rolesCtxDN
| fully-qualified DN |
none
|
The fixed DN of the context to search for user roles. This is not the DN where the actual roles are, but the DN where the objects containing the user roles are. For example, in a Microsoft Active Directory server, this is the DN where the user account is.
|
roleFilter
| LDAP filter string |
none
|
A search filter used to locate the roles associated with the authenticated user. The input username or
userDN obtained from the login module callback is substituted into the filter anywhere a {0} expression is used. The authenticated userDN is substituted into the filter anywhere a {1} is used. An example search filter that matches on the input username is (member={0}). An alternative that matches on the authenticated userDN is (member={1}).
|
roleAttributeIsDN | true or false
| false
|
Whether or not the
roleAttributeID contains the fully-qualified DN of a role object. If false, the role name is taken from the value of the roleNameAttributeId attribute of the context name. Certain directory schemas, such as Microsoft Active Directory, require this attribute to be set to true.
|
defaultRole
|
Role name
|
none
|
A role included for all authenticated users
|
parseRoleNameFromDN
| true or false
| false
|
A flag indicating if the DN returned by a query contains the roleNameAttributeID. If set to
true, the DN is checked for the roleNameATtributeID. If set to false, the DN is not checked for the roleNameAttributeID. This flag can improve the performance of LDAP queries.
|
parseUsername
| true or false
| false
|
A flag indicating if the DN is to be parsed for the username. If set to
true, the DN is parsed for the username. If set to false the DN is not parsed for the username. This option is used together with usernameBeginString and usernameEndString.
|
usernameBeginString
|
string
|
none
|
Defines the string which is to be removed from the start of the DN to reveal the username. This option is used together with
usernameEndString.
|
usernameEndString
|
string
|
none
|
Defines the string which is to be removed from the end of the DN to reveal the username. This option is used together with
usernameBeginString.
|
roleNameAttributeID
| attribute | name
|
Name of the attribute within the
roleCtxDN context which contains the role name. If the roleAttributeIsDN property is set to true, this property is used to find the role object's name attribute.
|
distinguishedNameAttribute
| attribute | distinguishedName
|
The name of the attribute in the user entry that contains the DN of the user. This may be necessary if the DN of the user itself contains special characters (backslash for example) that prevent correct user mapping. If the attribute does not exist, the entry's DN is used.
|
roleRecursion
| integer | 0
|
The numbers of levels of recursion the role search will go below a matching context. Disable recursion by setting this to
0.
|
searchTimeLimit
| integer | 10000 (10 seconds)
|
The timeout in milliseconds for user or role searches.
|
searchScope
|
One of:
OBJECT_SCOPE, ONELEVEL_SCOPE, SUBTREE_SCOPE
| SUBTREE_SCOPE
|
The search scope to use.
|
allowEmptyPasswords
| true or false
| false
|
Whether to allow empty passwords. Most LDAP servers treat empty passwords as anonymous login attempts. To reject empty passwords, set this to false.
|
referralUserAttributeIDToCheck
|
attribute
|
none
|
If you are not using referrals, this option can be ignored. When using referrals, this option denotes the attribute name which contains users defined for a certain role (for example,
member), if the role object is inside the referral. Users are checked against the content of this attribute name. If this option is not set, the check will always fail, so role objects cannot be stored in a referral tree.
|
| Code | RoleMapping
|
| Class | org.jboss.security.auth.spi.RoleMappingLoginModule
|
| Description |
Maps a role which is the end result of the authentication process to a declarative role. This module must be flagged as
