How to change user for Admin Server
Problem Statement:
S1DS 5.2(compressed archive) does not offer the option of specifying the
owner of the admin server during installation. When you specify
non-privilege user, such as nobody, for directory server, admin server is
also running as same non-privilage user as well as directory server.
Therefore, if you specify privilege port in unix (<1024) for the directory
server, this will result in not being able to start / restart the directory
server instance via the console.
Troubleshooting Steps:
If admin server is running as user except for root, you can't change the user
for admin server via cosole.
Here is a steps to change user for Admin server by hand.
** admin server should be stopped before conducting this procedure, but
ns-slapd for configuration instance should be on-line.
1. change directive named 'User' in
ServerRoot/admin-serv/config/magnus.conf to 'root' by text editor.
2. change file owner under ServerRoot/admin-serv to user you want as follows
a. # cd
b. # chown -R root *
3. change attribute ‘nsSuiteSpotUser’ of admin server configuration entry
in your Directorty Server like
dn: cn=configuration, cn=admin-serv-
Server, cn=Server Group, cn=
to the user you want to change to.
For example) in case of using ldapsearch
a. do the following ldapsearch to determine target entry
#./ldapsearch -p
dn:cn=configuration, cn=admin-serv-test, cn=Administration Server,
cn=Server Group,cn=test.example.com, ou=example.com, o=NetscapeRoot
nsSuiteSpotUser=nobody
#
b. modify usr in attribute nsSuiteSpotUser of this entry to ‘root’
# ldapmodify -p
cn=Server Group, cn=test.example.com, ou=example.com, o=NetscapeRoot
changetype: modify
replace: nsSuiteSpotUser
nsSuiteSpotUser: root
modifying entry cn=configuration, cn=admin-serv-test,
cn=Administration Server, cn=Server Group, cn=test.example.com,
ou=example.com, o=NetscapeRoot
^D
#
you can also do same modification via directory TAB in directory
server console.
Problem Statement:
What can happen if you delete your certificates and forget to disable
encryption on your ldap server is that your directory server will not
start the next time you go to restart it.

2.On all hosts, remove replication state.
– Use Console disable the replica role for userRoot.
– If a master, delete the changelog associated with the userRoot database
– restart the slapd process.
3.Reinitialize primary master with it’s own data, stripped of replication state
– invoke an in-line db2ldif dump, without the ( -r ) switch
– stop slapd
– classic ldif2db using the dump just created to rebuild database
– start slapd, validate basic serviceability
4.Configure Replication on master 1
– Use console to enable/ configure a changelog for userRoot
– Enable replication in a multi master role
5.Prepare seed LDIF
– invoke and in-line db2ldif dump, USING the ( -r ) switch. Confirm that ldif carries replication state data.
– Copy the seed LDIF to consumer (master 2)
6.Enable replication on master 2
– Enable / configure a changelog for userRoot
– Enable replication in a multi-master role
– stop slapd
– classic ldif2db import using the seed ldif from master1
– start slapd (master 2), validate basic serviceability
7.Test functional replication , both ways, master1 <-> master 2]]>
How to set up a reverse proxy using Apache 2.0.x and have it rewrite urls.
This is particularly useful if you’re using an Identity server internally and want to be able to access the server externally. You can set up an Apache reverse proxy server in your DMZ and allow it to do so. If you use Identity Server 6.3 or higher, you will not need to do this.
The sole purpose for this article is because we needed a workaround for a customer due to a problem with the older version of Identity server where for the logout button uses an absolute url rather than a relative url and it causes the link to be inaccessible.
Because the customer was doing this on Linux, the instructions here will be for Linux and will differ from what you would do in Solaris. If you wanted to do this in Solaris, you would need either more sources or you could install the binaries from http://www.blastwave.org or http://www.sunfreeware.org.
To start with, you will need Apache 2.0.x installed. You can verify this with:
rpm -qav | grep httpd
or
rpm -qav | grep apache (depending on which Linux distribution you have)
My output shows I have httpd-2.0.52-3.1 installed.
You will want to check to see that your Apache installation also includes the mod_proxy modules. You can check this with:
rpm -qil httpd
My output shows:
/usr/lib/httpd/modules/mod_proxy.so
/usr/lib/httpd/modules/mod_proxy_connect.so
/usr/lib/httpd/modules/mod_proxy_ftp.so
/usr/lib/httpd/modules/mod_proxy_http.so
Redhat Linux and Trustix Secure Linux both have these by default. I obviously can’t speak for all the other Linux distributions out there. If you don’t have these, you don’t want to continue. You will probably want to either find an rpm that has these or go and download the source and compile Apache with them.
Now, here comes the fun stuff. You will need to compile a new module – mod_proxy_html. You can download the module from: http://apache.webthing.com/mod_proxy_html/
You may want to follow this as a guide: http://www.apacheweek.com/features/reverseproxies
There are a few dependencies you will need to compile this module. For instance, you will definitely need a compiler and some libraries. Here’s a small list that I have installed on my box. You may need more.
gcc
httpd-devel-2.0.52-3.1
libxml2-2.6.16-3.i386.rpm
libxml2-devel-2.6.16-3.i386.rpm
zlib-devel-1.2.1.2-1.i386.rpm
To compile the module, run:
apxs -c -I/usr/include/libxml2 -i mod_proxy_html.c
After doing this, you should find the module located where your apache modules are stored like:
ls -l /usr/lib/httpd/modules/mod_proxy_html.so
-rwxr-xr-x 1 root root 59627 Apr 8 18:02 /usr/lib/httpd/modules/mod_proxy_html.so
Congratulations! You now have the module installed. You now have to configure it.
In my case, the apache configuration file is located in /etc/httpd/conf/httpd.conf
Here, I add where the modules are:
———————————————————————————————–
LoadFile /usr/lib/libxml2.so.2
LoadModule proxy_html_module modules/mod_proxy_html.so
———————————————————————————————–
Then, later in the file:
———————————————————————————————–
ProxyHTMLLogVerbose On
LogLevel Debug
ProxyRequests off
ProxyPass /amserver http://sapphire.atac.ebay.sun.com/amserver
ProxyPassReverse /amserver http://sapphire.atac.ebay.sun.com/amserver
ProxyPass /amconsole http://sapphire.atac.ebay.sun.com/amserver
ProxyPassReverse /amconsole http://sapphire.atac.ebay.sun.com/amserver
SetOutputFilter proxy-html
ProxyHTMLURLMap http://sapphire.atac.ebay.sun.com http://megatron.atac.ebay.sun.com i
———————————————————————————————–
What I’m doing here is rewrite the url for any requests that go into amconsole or amserver to go and grab the data from the sapphire machine. Any urls that are within the pages that point to sapphire will be rewritten as megatron.
All you have to do now is restart apache.
/usr/sbin/apachectl restart
That’s it! You now should be able to access http://megatron.atac.ebay.sun.com/amserver or
http://megatron.atac.ebay.sun.com/amconsole and get the same login screen and be able to navigate the entire Identity Server or whatever else you put behind the proxy.
