Hello all, I just joined this list and I was wondering if anyone could help with my problem or provide a link to a similar discussion if it has been held before. I successfully installed the redhat IPA on the server and on one client for starters. On the server, after creating ipa users through the web interface, I'm able to switch to the new ipa user (i had to edit the add the pam_mkdir module in the login and su pam.d files) However trying to switch user from the ipa-client is telling me 'account does not exist' ... Part of my /etc/nsswitch file on the client and on the server has the entry . passwd: files ldap shadow: files ldap group: files ldap The log file on the ipa-client is given below: Nov 21 14:12:33 phbdnssrv su: nss_ldap: failed to bind to LDAP server ldap://<a href="http://ipaserver.mydomain.com">ipaserver.mydomain.com</a>: Can't contact LDAP server Nov 21 14:12:33 phbdnssrv su: nss_ldap: could not search LDAP server - Server is unavailable Nov 21 15:44:49 phbdnssrv su: nss_ldap: failed to bind to LDAP server ldap://<a href="http://ipaserver.mydomain.com">ipaserver.mydomain.com</a>: Can't contact LDAP server Nov 21 15:44:49 phbdnssrv su: nss_ldap: could not search LDAP server - Server is unavailable My DNS seems to be up and it returns queries on both server and client...Please is there anything I could do and that I am missing. Thanks in advance ed -- Edward Popoola (RHCE, SCSA, C|EH)
