DESCRIPTION

Net::LDAP::Util is a collection of utility functions for use with the Net::LDAP modules.

FUNCTIONS

ldap_error_name ( NUM )

Returns the name corresponding with the error number passed in. If the error is not known the a string in the form "LDAP error code %d(0x%02X)" is returned.

ldap_error_text ( NUM )

Returns the text from the POD description for the given error. If the error code given is unknown then undef is returned.

ldap_error_desc ( NUM )

Returns a short text description of the error.

canonical_dn ( DN )

Returns the given DN in a canonical form. Returns undef if DN is not a valid Distinguished Name

It performs the following operations on the given DN

• Lowercases values that are # followed by hex.

• Uppercases type names.

• Removes the leading OID. characters if the type is an OID instead of a name.

• Escapes all RFC 2253 special characters, and any other character where the ASCII code is <32 or >= 127, with a backslash and a two digit hex code.

• Converts all leading and trailing spaces in values to be \20.

• If an RDN contains multiple parts, the parts are re-ordered so that the attribute names are in alphabetical order.

Note values that are hex encoded (ie start with a #) are not decoded. So SN=Barr is not treated the same as SN=#42617272
