AbstractSearchDnResolver

public AbstractSearchDnResolver()

Method Detail

getBaseDn

public String getBaseDn()

Returns the base DN.

Returns:

base DN

setBaseDn

public void setBaseDn(String dn)

Sets the base DN.

Parameters:

dn - base DN

getUserFilter

public String getUserFilter()

Returns the filter used to search for the user.

Returns:

filter for searching

setUserFilter

public void setUserFilter(String filter)

Sets the filter used to search for the user.

Parameters:

filter - for searching

getUserFilterParameters

public Object[] getUserFilterParameters()

Returns the filter parameters used to search for the user.

Returns:

filter parameters

setUserFilterParameters

public void setUserFilterParameters(Object[] filterParams)

Sets the filter parameters used to search for the user.

Parameters:

filterParams - filter parameters

getAllowMultipleDns

public boolean getAllowMultipleDns()

Returns whether DN resolution should fail if multiple DNs are found.

Returns:

whether an exception will be thrown if multiple DNs are found

setAllowMultipleDns

public void setAllowMultipleDns(boolean b)

Sets whether DN resolution should fail if multiple DNs are found. If false an exception will be thrown if resolve(User) finds more than one DN matching it's filter. Otherwise the first DN found is returned.

Parameters:

b - whether multiple DNs are allowed

getSubtreeSearch

public boolean getSubtreeSearch()

Returns whether subtree searching will be used.

Returns:

whether the DN will be searched for over the entire base

setSubtreeSearch

public void setSubtreeSearch(boolean b)

Sets whether subtree searching will be used. If true, the DN used for authenticating will be searched for over the entire getBaseDn(). Otherwise the DN will be searched for in the getBaseDn() context.

Parameters:

b - whether the DN will be searched for over the entire base

getDerefAliases

public DerefAliases getDerefAliases()

Returns how to dereference aliases.

Returns:

how to dereference aliases

setDerefAliases

Sets how to dereference aliases.

Parameters:

da - how to dereference aliases

getFollowReferrals

public boolean getFollowReferrals()

Returns whether to follow referrals.

Returns:

whether to follow referrals

setFollowReferrals
