NAME
kadm5.acl - Kerberos access control list (ACL) file
SYNOPSIS
/etc/krb5/kadm5.acl
DESCRIPTION
The ACL file is used by the kadmind(1M) command to determine which principals are allowed to perform Kerberos administration actions. For operations that affect principals, the ACL file also controls which principals can operate on which other principals. The location of the ACL file is determined by the acl_file configuration variable in the kdc.conf(4) file. The default location is /etc/krb5/kadm5.acl. For incremental propagation, see kadmind(1M). The ACL file must contain the kiprop service principal with propagation privileges in order for the slave KDC to pull updates from the master's principal database. Refer to the EXAMPLES section for this case. The ACL file can contain comment lines, null lines, or lines that contain ACL entries. Comment lines start with the pound sign (#) and continue until the end of the line. The order of entries is significant. The first matching entry specifies the principal on which the control access applies, whether it is on just the principal or on the principal when it operates on a target princi- pal. Lines containing ACL entries must have the following format: principal operation-mask [operation-target] principal Specifies the principal on which the operation-mask applies. Can specify either a par- tially or fully qualified Kerberos principal name. Each component of the name can be sub- stituted with a wildcard, using the asterisk ( * ) character. operation-mask Specifies what operations can or cannot be performed by a principal matching a particular entry. Specify operation-mask as one or more privileges. A privilege is a string of one or more of the following characters: a, A, c, C, d, D, i, I, l, L, m, M, p, P, u, U, x, or *. Generally, if the character is lowercase, the privi- lege is allowed and if the character is uppercase, the operation is disallowed. The x and * characters are exceptions to the uppercase convention. The following privileges are supported: a Allows the addition of principals or policies in the database. A Disallows the addition of principals or policies in the database. c Allows the changing of passwords for principals in the database. C Disallows the changing of passwords for principals in the database. d Allows the deletion of principals or policies in the database. D Disallows the deletion of principals or policies in the database. i Allows inquiries to the database. I Disallows inquiries to the database. l Allows the listing of principals or policies in the database. L Disallows the listing of principals or policies in the database. m Allows the modification of principals or policies in the database. M Disallows the modification of principals or policies in the database. p Allow the propagation of the principal database. P Disallow the propagation of the principal database. u Allows the creation of one-component user principals whose password can be validated with PAM. U Negates the u privilege. x Short for specifying privileges a, d,m,c,i, and l. The same as *. * Short for specifying privileges a, d,m,c,i, and l. The same as x. operation-target Optional. When specified, the privileges apply to the principal when it operates on the operation-target. For the operation-target, you can specify a partially or fully qualified Kerberos principal name. Each component of the name can be substituted by a wildcard, using the asterisk ( * ) character.
EXAMPLES
Example 1 Specifying a Standard, Fully Qualified Name The following ACL entry specifies a standard, fully qualified name: user/instance@realm adm The operation-mask applies only to the user/instance@realm principal and specifies that the principal can add, delete, or modify principals and policies, but it cannot change passwords. Example 2 Specifying a Standard Fully Qualified Name and Target The following ACL entry specifies a standard, fully qualified name: user/instance@realm cim service/instance@realm The operation-mask applies only to the user/instance@realm principal operating on the service/instance@realm target, and specifies that the principal can change the target's password, request information about the tar- get, and modify it. Example 3 Specifying a Name Using a Wildcard The following ACL entry specifies a name using a wildcard: user/*@realm ac The operation-mask applies to all principals in realm realm whose first component is user and specifies that the principals can add principals and change passwords. Example 4 Specifying a Name Using a Wildcard and a Target The following ACL entry specifies a name using a wildcard and a target: user/*@realm i */instance@realm The operation-mask applies to all principals in realm realm whose first component is user and specifies that the principals can perform inquiries on principals whose second component is instance and realm is realm. Example 5 Specifying Incremental Propagation Privileges The following ACL entry specifies propagation privileges for the kiprop service principal: kiprop/slavehost@realm p The operation-mask applies to the kiprop service principal for the specified slave host slavehost in realm realm. This specifies that the associated kiprop service principal can receive incremental principal updates.
