LMS 4.2.5 - Slow Homepage login with TACACS+ module enabled

Hi all,

having setup TACACS+ Login module Login into Homepage takes about 80 sec.

 

Reverting back to local-Login module Login into Homepage takes about 20 sec.

 

Anybody out there able to help in Tuning TACACS+ Login module for Performance.

 

During Troubleshooting we discovered that request from LMS to TACACS+-Server (ACS)

is done after 60 sec of Login attempt, it seems that LMS slows down Login Performance here.

 

Thanks for any feedback

 

Lothar

Update:

Digging deeper we discovered a DNS-Issue, dns-resover on server was configured to use two different dns-servers.

And also Prime seems to resolve hostname tacacs for ACS-Server configured in TACACS+ Login-Module -> adding an entry in /etc/hosts with IP of ACS and hostname tacacs also speeds up login-waittime from 80 sec to 20 sec.

I'm not quite sure why TACACS+ Login-Module depends so heavy on DNS?

Hi Lothar,

Although, this is not a very uncommon issue, but the remedies differs in each case.

You can try below things:-

1. Restart the daemon manager

2. If the windows server, check the services, these setting are never recommended to have in startup type of automatic except deamon manager, CSCW rsh/scp/syslog/tftp services.
