Account get locked in first failed login attempt

[Vikash Chandra Ansh]

Hi all,

I am getting an unusual behaviour. Currently I am using four ldaps for authentication. If suppose a user has entered wrong credentials at once,account is locked.

Kindly help me to resolve this.

I have added authentication type as authenticated.

[Ray Bon]

Vikash,

See https://apereo.github.io/cas/6.1.x/installation/Configuring-Authentication-Throttling.html

Also check you ldap settings/logs to see if the issue is there.

I have tried all the possible ways.. But could not find the conclusion..

I have used below properties.

#${configurationKey}.ldapUrl=ldaps://ldap1.example.edu ldaps://ldap2.example.edu ldaps://ldap3.example.edu ldaps://ldap4.example.edu

#${configurationKey}.bindDn=cn=Directory Manager,dc=example,dc=org
#${configurationKey}.bindCredential=Password

#${configurationKey}.poolPassivator=BIND
#${configurationKey}.connectionStrategy=
#${configurationKey}.providerClass=org.ldaptive.provider.unboundid.UnboundIDProvider
#${configurationKey}.connectTimeout=PT5S

#${configurationKey}.minPoolSize=3
#${configurationKey}.maxPoolSize=10
#${configurationKey}.validateOnCheckout=true
#${configurationKey}.validatePeriodically=true
#${configurationKey}.validatePeriod=PT5M
#${configurationKey}.validateTimeout=PT5S
#${configurationKey}.failFast=true
#${configurationKey}.idleTime=PT10M
#${configurationKey}.prunePeriod=PT2H
#${configurationKey}.blockWaitTime=PT3S
#${configurationKey}.useSsl=true
#${configurationKey}.useStartTls=false
#${configurationKey}.responseTimeout=PT5S
#${configurationKey}.allowMultipleDns=false
#${configurationKey}.allowMultipleEntries=false
#${configurationKey}.followReferrals=false
#${configurationKey}.binaryAttributes=objectGUID,someOtherAttribute 

Kindly guide me what to do.

Thanks and regards

Vikash,

Cas log in throttling is handled by these (and related settings), not ldap settings:

# Authentication Throttling

# https://apereo.github.io/cas/5.1.x/installation/Configuration-Properties.html#authentication-throttling

# default is by ip address only

# enable following to use user name and ipaddress

# cas.authn.throttle.usernameParameter=username

# this is a rate of failed attempts: threshold / rangeSeconds

cas.authn.throttle.failure.threshold=1

cas.authn.throttle.failure.rangeSeconds=3

In your log file, check what happens between cas and ldap:

        <AsyncLogger name="org.ldaptive" level="${sys:ldap.log.level}" includeLocation="true" />

Hi Ray,

I am asking a different concept. I am looking for a concept of passivator where connection pool gets blocked after a failed login attempt. If we use more than one ldap. During unsuccessful login ,bind will happen on both simultaneously which will result to account lock.

I have tried using the property poolpassivator=BIND if I m using ldap type as AUTHENTICATED.

Still account get locked after 2 unsuccessful login attempt

Thanks and regards.

Can you post the CAS logs that show simultaneous binds?

Hi Daniel,

Could you please suggest what to do next. I am facing the same issue like Eric is facing, and same logs are getting generated for me.

 For all the ladps we are using the same BIND.

I tried to implement the concept of passivators and used the property poolpassivator=BIND. but this doesnt help.

 Moreover could you plzz suggest like if use more than one ldap, property should be like this:-

cas.authn.ldap[0].type=AUTHENTICATED
cas.authn.ldap[0].ldapUrl=ldaps://dcsvc-300.ad.wichita.edu
ldaps://dcsvc-307.ad.wichita.edu ldaps://latitude.ad.wichita.edu
ldaps://longitude.ad.wichita.edu 

or

cas.authn.ldap[0].ldapUrl=ldaps://dcsvc-300.ad.wichita.edu
cas.authn.ldap[1].ldapUrl=

  cas.authn.ldap[2].ldapUrl =

cas.authn.ldap[3].ldapUrl   =

 As in the Eric logs I cant figure it out on which ldap request is going for a login attemp and on which it failed. Its taking 4 ldaps as a whole.

Vikash,

Have you tried checking on LDAP side server logs?, open 4 windows with logs tailed, and you can use grep for filtering.

In the absence of logs I really can't make a suggestion. Continue watching the other thread and hopefully Eric will hit on a solution.
