A Dictionary value can be either a string, or an array, or a dictionary, so the format definition is recursive.
If you want to include the quotation mark into a string, include the backslash symbol and the quotation mark, if you want to include the backslash symbol into a quoted string, include 2 backslash symbols.
You can use the \r symbol combination to include the Return symbol into a string, you can use the \n symbol combination to include the Line Feed symbol into a string, and your can use the \e symbol combination to include the system-independent End-Of-Line symbol(s) into a string.
You can use the \t symbol combination to include the Tab symbol into a string.
You can use the \nnn symbol combination include any symbol into a string, if nnn is a 3-digit decimal number equal to the code of the desired symbol.
An array element can be either a string, or an array, or a dictionary.
Any number of spaces, tabulation symbols, and/or line breaks (end-of-line symbols) can be placed between a parentheses and an element, and between an element and a comma sign.
The value element in any key-value pair can be some other array and/or dictionary.
Any number of spaces, tabulation symbols, and/or line breaks (end-of-line symbols) can be placed between a bracket and a pair, around the equal sign, and around the semicolon sign.
Below is the formal syntax for the Dictionary and Array formats:
a-symbol ::= A .. Z | a .. z | 0 .. 9 atom ::= 1*a-symbol s-symbol ::= any printable symbol except " and \ | \\ | \" | \r | \n | \e | \nnn string ::= " 1*s-symbol " | atom array ::= ( [object [, object ...]] ) dictionary ::= { [string = object ; [string = object ; ...]] } object ::= string | array | dictionary |
Several different database types are supported, and the database type is defined by the database file (or directory) name extension.
For all database types, the CommuniGate Pro Server provides required update synchronization mechanisms to let several processing threads retrieve and update database records simultaneously.
The first file line is a special one, it contains tab-delimited strings with the database field names. Below is a sample of a .tbd database with the mail, cn and Limit fields and 3 records. The tabulation signs are marked as t :
|
If you want to add a field to the database, stop the server, and add the new field name to the first file line, separating it with the tabulation sign.
Database fields can contain complex (dictionary-type, array-type) data elements. These elements are stored in the text format diescribed in the previous section.
The .ldp database file has the dictionary format (see above) with the following data:
Key Name | Type | Value |
---|---|---|
Server | string | the name or the IP address of the LDAP server |
Fields | array | database field names, the first name should specify the "key" field |
LoginName | stringthe DN-name to use when logging into the LDAP server | |
LoginPassword | string | the password to use when logging to the LDAP server |
