24 Net::LDAP::LDIF provides a means to convert between Net::LDAP::Entry
25 objects and LDAP entries represented in LDIF format files. Reading and
26 writing are supported and may manipulate single entries or lists of
27 entries.
28 As when reading an entire file into memory with perl normally, take
30 into account the possibility of memory use when loading an LDIF file in
31 one go.
32
34 new ( FILE )
35 Open the file read-only. "FILE" may be the name of a file or an
36 already open filehandle. If "FILE" begins or ends with a "⎪" then
37 "FILE" will be passed directly to "open".
38 new ( FILE, MODE, OPTIONS )
40 Open the file with the given "MODE", eg "w" or "a". "FILE" may be
41 the name of a file or an already open filehandle. If "FILE" begins
42 or ends with a "⎪" then "FILE" will be passed directly to "open".
43 encode => 'none' ⎪ 'canonical' ⎪ 'base64'
45 Some DN values in LDIF cannot be written verbatim and have to
46 be encoded in some way:
47 'none'
49 The default.
50 'canonical'
52 See "canonical_dn" in Net::LDAP::Util.
53 'base64'
55 Use base64.
56 onerror => 'die' ⎪ 'warn' ⎪ undef
58 Specify what happens when an error is detected.
59 'die'
61 "Net::LDAP::LDIF" will croak with an appropriate message.
62 'warn'
64 "Net::LDAP::LDIF" will warn with an appropriate message.
65 undef
67 "Net::LDAP::LDIF" will warn with an appropriate message if
68 "-w" is in effect. The method that was called will return
69 "undef".
70 change => 1
72 Write entry changes to the LDIF file instead of the entries
73 itself. I.e. write LDAP operations acting on the entries to
74 the file instead of the entries contents.
75 lowercase => 1
77 Convert attribute names to lowercase when writing.
78 sort => 1
80 Sort attribute names when writing entries according to the
81 rule: objectclass first then all other attributes alphabeti‐
82 cally sorted
83 version => '1'
85 Set the LDIF version to write to the resulting LDIF file.
86 According to RFC 2849 currently the only legal value for this
88 option is 1.
89 When this option is set Net::LDAP::LDIF tries to adhere more
91 strictly to the LDIF specification in RFC2489 in a few places.
92 The default is undef meaning no version information is written
94 to the LDIF file.
95 wrap => 78
97 Number of columns where output line wrapping shall occur.
98 Default is 78. Setting it to 40 or lower inhibits wrapping.
100 raw => REGEX
102 Use REGEX to denote the names of attributes that are to be con‐
103 sidered binary in search results.
104 When running on Perl 5.8 and this option is given Net::LDAP
106 converts all values of attributes not matching this REGEX into
107 Perl UTF-8 strings so that the regular Perl operators (pattern
108 matching, ...) can operate as one expects even on strings with
109 international characters.
110 If this option is not given or the version of Perl Net::LDAP is
112 running on is too old strings are encodeed the same as in ear‐
113 lier versions of perl-ldap.
114 Example: raw => qr/(?i:^jpegPhoto⎪;binary)/
116
118 read_entry ( )
119 Read one entry from the file and return it as a "Net::LDAP::Entry"
120 object.
121 eof ( )
123 Returns true when the end of the file is reached.
124 write_entry ( ENTRIES )
126 Write the entries to the LDIF file.
127 write_version ( )
129 If the object's version is defined, this method allows to
130 explicitely write the version before an entry is written.
131 If not called explicitely, it gets called automatically when writ‐
133 ing the first entry.
134 version ( [ VERSION ] )
136 If called without arguments it returns the version of the LDIF file
137 or undef if no version has been set. If called with an argument it
138 sets the LDIF version to VERSION.
139 According to RFC 2849 currently the only legal value for VERSION is
141 1.
142 handle ( )
144 Returns the file handle the "Net::LDAP::LDIF" object reads fromi or
145 writes to.
146 done ( )
148 This method signals that the LDIF object is no longer needed. If a
149 file was opened automatically when the object was created it will
150 be closed. This method is called automatically via DESTROY when the
151 object goes out of scope.
152 error ( )
154 Returns error message if error was found.
155 error_lines ( )
157 Returns lines that resulted in error.
158 current_entry ( )
160 Returns the current "Net::LDAP::Entry" object.
161 current_lines ( )
163 Returns the lines that generated the current "Net::LDAP::Entry"
164 object.
165 next_lines ( )
167 Returns the lines that will generate the next "Net::LDAP::Entry"
168 object.
