DS attribute encryption (ETA) properties
Directory Server allows you to encrypt individual attributes to protect sensitive information stored in the directory. The encryption does not prevent client applications from reading the attributes. Instead it works at the database index file level to prevent users with access to read database index files from being able to search through the indexes for sensitive information.
For example, before attribute encryption is configured for
uid attributes, a user with read access to database index files could easily find out that
bjensen is a
uid attribute value:
$ strings example_uid.db3 | grep bjensen =bjensen $
uid attributes are encrypted, the job is not so easy:
$ strings example_uid.db3 | grep bjensen $
Notice however that encrypted RDN values are not fully hidden. Instead they appear in clear in the DN index:
$ strings example_entrydn.db3 | grep bjensen =uid=bjensen,ou=people,dc=example,dc=com =uid=bjensen,ou=people,dc=example,dc=com $
Directory Server uses a cipher to encrypt a specified attribute in a given suffix. This property specifies the cipher used.
The following property values are supported:
DES block cipher
Triple-DES block cipher
RC2 block cipher
RC4 stream cipher
AES 128-bit block cipher
AES 256-bit block cipher
CAMELLIA 128-bit block cipher
CAMELLIA 256-bit block cipher
Syntax values shown in lower case or partly in lower case are literal values.
Those shown in upper case are syntax types, defined as follows:
A valid attribute type name such as
A valid distinguished name such as
A duration specified in months (
M), weeks (
w), days (
d), hours (
h), minutes (
m), seconds (
s), and miliseconds (
ms), or some combination with multiple specifiers. For example, you can specify one week as
604800s. You can also specify one week as
DURATION properties typically do not each support all duration specifiers (
Mwdhms). Examine the output of
dsconf help-properties for the property to determine which duration specifiers are supported.
A valid e-mail address.
An IP address or host name.
A positive integer value between 0 and the maximum supported integer value in the system address space. On 32-bit systems,
2147483647. On 64-bit systems,
An interval value of the form
0123456, where the first element specifies the starting hour, the next element the finishing hour in 24-hour time format, from
2359, and the second specifies days, starting with Sunday (
0) to Saturday (
An IP address or range of address in one of the following formats:
IP address in dotted decimal form.
IP address and bits, in the form of network number/mask bits.
IP address and quad, in the form of a pair of dotted decimal quads.
All address. A catch-all for clients that are note placed into other, higher priority groups.
0.0.0.0. This address is for groups to which initial membership is not considered. For example, for groups that clients switch to after their initial bind.
IP address of the local host.
A valid LDAP URL as specified by RFC 2255 (
A memory size specified in gigabytes (
G), megabytes (
k), or bytes (
MEMORY_SIZE properties cannot combine multiple specifiers. However,
MEMORY_SIZE properties allow decimal values, for example, 1.5M.
cn (common name).
A three-digit, octal file permissions specifier. The first digit specifies permissions for the server user ID, the second for the server group ID, the last for other users. Each digit consists of a bitmask defining read (
4), write (
2), execute (
1), or no access (
0) permissions, thus
640 specifies read-write access for the server user, read-only access for other users of the server group, and no access for other users.
The full path to the file from which the bind password should be read.
A valid, absolute file system path.
A DirectoryString value, as specified by RFC 2252 (
An SSL cipher supported by the server. See the Reference for a list of supported ciphers.
An SSL protocol supported by the server. See the Reference for a list of supported protocols.
A time of the form hhmm in 24-hour format, where hh stands for hours and mm stands for minutes.
