Getting apache to see a LDAP group membership change
trying to implement authz to a webpage using require ldap-group. It works, except I need to do apachectl restart before the server will observe an add or a delete to the group.
Seems like apache is acquiring the group membership at startup & caching it.
It's a static group.
I have apache 2.2 on AIX and TDS LDAP.
We want to automate group member adds/deletes, which implies that we need to automate refreshing the server's knowledge of the group. Possible solutions I've wondered about
:
- using dynamic groups (membership would be evaluated on every authz rather than the principal/user being compared against a cached list). This may be conceptually correct but is not an option given our schema.
- doing something fugly like require ldap-attribute is-member-yatta-blah. I should be able to use require ldap-group.
- driving a apachectl refresh out of the add/delete automation. I'd do it with ssh to a public-key-protected login on the servers running apache, as long as that doesn't make our security heads hurl.
- something in HTML that tells the server to refresh its cached image of group contents ?
ideas appreciated

On Solaris, a user is limited to being a member of a maximum of 16 groups. Could someone tell me where this limit comes from, i.e. is it NIS, or Solaris, or NFS that is imposing this limit?
What is the work-around to remove this limitation? (4 Replies)

rpccp_add_member
add member(1m) add member(1m)
NAME
add member - Adds a member to a group in a name service entry; if the specified entry does not exist, creates the entry
SYNOPSIS
rpccp add member group-entry-name -m member [-s syntax]
OPTIONS
Declares the name of a member to be added to the specified group entry (required).
You can add only one member at a time. Indicates the name syntax of the entry name (optional). The only value for this option is the dce
name syntax, which is the default name syntax. Until an alternative name syntax becomes available, specifying the -s option is unnecessary.
ARGUMENTS
Specifies the name of the target group. For an entry in the local cell, you can omit the cell name and specify only the cell-relative
name.
DESCRIPTION
The add member command adds a member to a group in a name service entry. The name of the entry containing the group and the name of the
new group member are required. The entry of a group may have been created previously (by either the add entry or add member command). If
the specified entry does not exist, the add member command tries to create the entry.
Privilege Required
You need both read permission and write permission to the CDS object entry (the target group entry). If the entry does not exist, you also
need insert permission to the parent directory.
NOTE
This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE.
EXAMPLES
The following commands run RPCCP and add the member /.:/LandS/anthro/Cal_host_3 to the group /.:/LandS/anthro/Calendar_group: $ rpccp
rpccp> add member > -m /.:/LandS/anthro/Cal_host_3 > /.:/LandS/anthro/Calendar_group
RELATED INFORMATION
Commands: remove group(1m), remove member(1m), show group(1m)
